About Hornfels Hide. A fine-grained metamorphic rock composed of a mosaic of equidimensional grains without preferred orientation and usually formed by contact metamorphism. Porphyroblasts or relict phenocrysts may be present in the granoblastic matrix. See Also: calc-silicate hornfels, pelitic hornfels, magnesian hornfels.

What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.It has a composition similar to gabbro.The difference between basalt and gabbro is that …

Hornfels was formed when magma (now database) cut through the older shale and sandstone and 'cooked' (melted) the adjacent shale and sandstone. Hornfels is relatively low in silica.
