Bit of a headscratcher today. When a pyroxene and a pyroxene love each other very much...?
(These rocks are gay!)

Made good use of the large rocks that were dug up installing the fence by lining the fire pit. This part of the yard is near the back porch, but on a slope where a tree stump used to be. The pit was expanded into the hillside and limited downward by a very large rock that makes a solid base.

And the bowl back on the stand! Good timing because the weather is ready for a campfire and my firewood bin from the woodshop is overflowing.

Decided to try my hand at rendering. Was feeling uncertain at first but I think I like the final result!
This is my oc Dia by the way (from the word Diabase, like Hal - Halite)
There's not much to say about them because I didn't create them as another character, but rather as a self insert instead of the hatchling. I tried to imagine how my facial features would look like on a hearthian and Dia was born

Philly! I will be leading a trip to one of my favorite post-industrial forests with the Philadelphia Botanical Club on Sunday June 4th. It's at State Gameland 43 at St. Peters.
Things we will be likely to see: quarry spoil piles and associated novel habitats, post-industrial ruins, rich fern and wildflower assemblages, an assortment of parastic and hemiparasitic plants, influence of geology on plant communities (when the diabase stops and the sandstone starts, the forest gets REALLY different), cool millipedes, terrible funny graffiti, local heavy metal teenagers smoking weed, and much more. There is a cool bakery nearby for refreshment that makes "black granite cake" in honor of all the black granite/diabase deposits that shaped the town's history.
The trip is free and open to everyone! Share with your friends!

In 962 AD, near the town of Laon in Picardy, France, a small incident with a donkey played a major role in advancing the power of the kings of France. In the region, there was an extremely powerful lord, Count Heribert II of Vermandois.
He had recently been on a campaign within France and amassed an impressive level of power and influence. As he was traveling to Laon he decided to rest inside the city and, at the same time, test the loyalty of the citizens of Laon. To do this, he ordered that horses and donkeys from all around should be brought to him and presented at the city’s gates. A small peasant happened to own a donkey made of diabase, a very strong and uniquely formed alloy of minerals with a rare color and superior strength.
The diabase donkey presented itself to Count Heribert as a perfect symbol of strength and loyalty, and he was so impressed that he made this donkey his new symbol of power and adopted it as the emblem of Laon. Count Heribert was so pleased with this gift, that he even stopped his campaign and allowed Laon to prosper as a city of his rule. After this incident, the diabase donkey became a symbol of strength, loyalty, and prosperity in the region.
The diabase donkey is an important reminder of how loyalty can be rewarded and how a single event can significantly increase the power and influence of a ruler. This story of the donkey made of diabase has been remembered in the Picardy region and is still cherished by many.

A thin section is about as flat as you can get, but put enough feldspar next to each other and it can feel a bit like falling into your microscope. Some lovely diabase today!

High geomagnetic field intensity recorded by anorthosite xenoliths requires a strongly powered late Mesoproterozoic geodynamo
Obtaining estimates of Earth’s magnetic field strength in deep time is complicated by nonideal rock magnetic behavior in many igneous rocks. In this study, we target anorthosite xenoliths that cooled and acquired their magnetization within ca. 1,092 Ma shallowly emplaced diabase intrusions of the North American Midcontinent Rift. In contrast to the diabase which fails to provide reliable paleointensity estimates, the anorthosite xenoliths are unusually high-fidelity recorders yielding high-quality, single-slope paleointensity results that are consistent at specimen and site levels. An average value of ∼83 ZAm2 for the virtual dipole moment from the anorthosite xenoliths, with the highest site-level values up to ∼129 ZAm2, is higher than that of the dipole component of Earth’s magnetic field today and rivals the highest values in the paleointensity database. Such high intensities recorded by the anorthosite xenoliths require the existence of a strongly powered geodynamo at the time. Together with previous paleointensity data from other Midcontinent Rift rocks, these results indicate that a dynamo with strong power sources persisted for more than 14 My ca. 1.1 Ga. These data are inconsistent with there being a progressive monotonic decay of Earth’s dynamo strength through the Proterozoic Eon and could challenge the hypothesis of a young inner core. The multiple observed paleointensity transitions from weak to strong in the Paleozoic and the Proterozoic present challenges in identifying the onset of inner core nucleation based on paleointensity records alone.

Module 4: Public Art
As your are commuting through the Midpoint Memorial bridge in the South West Florida that connects Cape Coral and Fort Myers you are you may see a nearly 20-foot commemoration of five marines and a navy hospital corpsman raising the American flag on Mount Suribachi at the highest point which stands at 560 feet on the small island of Iwo Jima. This statue is one of three original sculptures created by the sculptor named Felix de Weldon. One of the sculptures stands near the Arlington National Cemetery in Virginia while the other one is located at the Iwo Jima Monument and Memorial Museum State Historic Site in Harlingen, Texas. These monuments were made in honor of all Marinies who have given there life in defense of the United States since 1775. These war memorials were inspired by a 1945 photograph taken by Associated Press combat photographer Joe Rosenthal. After seeing that image. Felix de Weldon proposed a sculpture based of the photography to congress, but funding was no possible due to complications in the war. However, a federal foundation in 1947 was establish to raise funds for the main memorical located in Arlington. The Memorial was approved by Congress in 1951 and was accepted by the Marine Corps League, who also selected him to be the sculpture of this said memorial. In total, this sculpture took three years to create a full-sized plaster, having the figures be 32 feet tall. The bottom base is made of black diabase granite from a quarry in Lönsboda, a small town in the southernmost province of Sweden. The overall sculpture features numerous inscriptions commorrating those in the original photograph, each being recoginzed for their overall roll in the Battle of Iwo Jima. Smaller replicas of this sculpure are the ones found in Florida and Texas.

🏰 Vorontsov Palace - One of the most popular places in Crimea among tourists, along with Massandra, Livadia Palace and Swallow's Nest.
📍 The Vorontsov Palace is located in Alupka, 15 km from Yalta.
⚒ The palace was built of diabase (a volcanic rock with properties stronger than granite) in the English Gothic style.
60,000 servants and soldiers worked on its construction for 20 years (from 1828 to 1848).
9 million silver rubles were spent.
🏯 In 1921 the palace became a museum, but during the Great Patriotic War it was looted.
The amount of damage was estimated at 5 million rubles.
In 1956, a museum was reopened in the castle, and since 1990 the Alupka Palace and the Park Museum-Reserve have been located here.
🌳 The palace is surrounded by a centuries-old park, which contains 200 species of trees and exotic plants.

The Ultimate Guide to Insulation Batts Everything You Need to Know
Welcome to the ultimate guide on insulation batts. If you're looking to improve the comfort and energy efficiency of your home or building, insulation batts Adelaide are a fantastic solution.
In this comprehensive guide, we will walk you through everything you need to know about insulation batts, from understanding the different types to installation techniques and maintenance tips. So, let's dive right in and explore the world of insulation batts.
What are Insulation Batts?
Insulation batts are thick pieces of material that are used to insulate walls, ceilings, and floors. They are designed to reduce heat transfer and keep your indoor space comfortable all year round. Insulation batts work by trapping air, which acts as a barrier against heat flow.
By installing insulation batts, you can significantly improve the energy efficiency of your home or building, reducing heating and cooling costs.
Types of Insulation Batts
Fiberglass Insulation
Fiberglass insulation batts are perhaps the most common and widely used type of insulation. They are made from tiny glass fibres that are formed into batts or rolls. Fiberglass insulation batts Adelaide offer several benefits, including fire resistance, affordability, and ease of installation.
They are available in various sizes and thicknesses to suit different insulation needs. When installing fibreglass insulation batts, make sure to wear protective clothing and follow the manufacturer's instructions for safe and effective installation.
Mineral Wool Insulation
Mineral wool insulation batts, also known as rock wool insulation, are made from natural minerals such as basalt or diabase. These batts are known for their excellent soundproofing properties, making them a popular choice for reducing noise transmission between rooms or floors. Mineral wool insulation batts are also resistant to pests, mould, and mildew.
Cellulose Insulation
Cellulose insulation batts are an eco-friendly option, as they are made from recycled paper and treated with fire-retardant chemicals. These batts have a high R-value, which measures the insulation's resistance to heat flow. Cellulose insulation batts are effective in controlling moisture and can be installed using various methods, such as blowing or dense packing.
Factors to Consider When Choosing Insulation Batts
R-Value
The R-value is a measure of the insulation's thermal resistance. It indicates how well insulation can resist heat flow. The higher the R-value, the better the insulation's performance. When choosing insulation batts, consider the recommended R-values for your specific climate zone.
Health and Safety Considerations
While insulation batts are generally safe to use, it's important to be aware of potential health concerns during installation or removal. Fiberglass insulation can cause skin irritations and respiratory issues if not handled properly.
Therefore, it's crucial to wear protective clothing, gloves, and masks when working with insulation batts. If you have allergies or sensitivities, it's best to consult a professional insulation installer.
Environmental Impact
Different types of insulation materials have varying environmental impacts. Fiberglass insulation is made from recycled glass, making it a sustainable choice. Mineral wool insulation is made from natural minerals, but the production process can involve energy-intensive procedures.
Final Thoughts
Let’s hope that this comprehensive guide has provided you with valuable insights into the world of insulation batts, from understanding the different types to installation techniques and maintenance tips. By considering insulation batts Adelaide for your home or building, you can significantly improve energy efficiency, reduce heating and cooling costs, and create a more comfortable indoor environment. Stay cosy and energy-efficient.
