This may be a fault breccia or cataclasite which is formed by the fracturing of rocks during fault movement.

When ice forms in cracks in rocks, the kind of weathering is known as mechanical weathering. The type of mechanical weathering that freezes and thaws is frost wedging.
Sill forms when magma flows in a horizontal direction along rock layers.
