Slate and shale originate from different geological processes. Slate is a metamorphic rock that forms from the compression of clay and silt sediments over long periods. On the other hand, shale is a sedimentary rock that develops from the accumulation of mud, clay, and organic matter that undergo compaction and cementation. Physical Characteristics
When shale and fine quartz particles get buried in the earth's crust, underground heat or magma from molten rock and heavy pressure (arising from tectonic movements) metamorphose the clay minerals to form chlorite …
The softest mineral known is talc. It has a rating of 1 on the Mohs hardness scale, which measures the relative hardness of different minerals. Talc is so soft that it can be easily scratched by a fingernail. Is sandstone soft or hard. Sandstone falls on the softer side of the rock hardness spectrum.
The rock is identifiable by its finely grained texture and foliated appearance. To tell slate from shale, one can look for flat sheet layers, test for hardness, and examine the distinct layers visible in slate. Slate is a low-grade metamorphic rock that …
The Young's modulus and hardness of bulk shale generally increase with increasing maturity. This is closely related to the hardening of organic matter and clay matrix, …
