Basalt - Wikipedia
Basalt is an aphanitic (fine-grained) igneous rock containing 45–53% silica and less than 10% feldspathoid by volume, with at least 65% of the rock consisting of feldspar in the form of plagioclase. This places basalt in the B field of the TAS classification or the gabbro fields of the QAPF diagram. Basalt is usually dark grey to black in colour, but can exhibit a wide range of shading.
Amending highly weathered soils with finely …
1-8-2002 · The basalt rock dust amendment has an abrasion pH of about pH 9, presumably due to the release of silicate ions upon contact with water, and their subsequent hydrolysis to poorly dissociated silicic acid. It would be expected, therefore, that application of the ameliorant to soil would have a …

basalt | Definition, Properties, & Facts | Britannica
Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a stone and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt in this article.
The Slow-Release Benefits of Basalt
For balancing overall soil health, basalt stands out from other rock materials. Created through the cooling and solidification of magma and lava, basalt is the rock material that makes up most of the soils around the world. Compared to other volcanic rocks that are high in quartz, basalt …

Do Rocks Affect the pH of Aquarium Water?
Another means of testing an unknown rock is to fill a bucket with water from the water source you plan to use. Then test and record the pH, hardness, nitrate and phosphate. Place the rock in the bucket and let it soak for a week, then test the water again. If there are no changes, the rocks are not likely to cause a problem in your aquarium.
