The difference between hornfels and soapstone is that.

Because temperature differences between the surrounding rock and the intruded magma are larger at shallow levels in the crust, contact metamorphism is usually referred to as high temperature, low pressure metamorphism.

Hornfels are generally products of heated recrystallization of the original rock (typically ...

The majority of rocks have a spotted appearance, like the hornfels in Figure 14.36. The spots are altered cordierite porphyroblasts. Figure 10.2 is a picture of a different biotite hornfels, and Figure 13.24 is a picture of a hornblende hornfels from near Wawa, Ontario. Both formed by contact metamorphism of a pelitic rock.

Hornfels is another non-foliated metamorphic rock that normally forms during contact metamorphism of fine-grained rocks like mudstone or volcanic rocks. How are hornfels made?

The word metamorphism comes from ancient Greek words for “change” (meta) and “form” (morph). The type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith.

A metamorphic facies is a set of mineral assemblages in metamorphic rocks formed under similar pressures and temperatures.

ADVERTISEMENT A variety of sedimentary, igneous, and metamorphic rocks can be the protolith of hornfels. Common protoliths of hornfels include sedimentary rocks such as shale, siltstone, sandstone, limestone and dolomite; igneous rocks such as basalt, gabbro, rhyolite, granite, andesite and diabase; or, metamorphic rocks such as schist and gneiss.It has a deep and mystical tone, whereas lapis lazuli features a royal blue finish. Another key difference between these two stones is the specks of gold found throughout lapis lazuli.

The type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith.Metamorphic rock, deformed during the Variscan orogeny, at Vall de Cardós, Lérida, Spain. Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure ... It may be schistose or massive. Soapstone is formed by metamorphism of ultramafic protoliths (eg dunite or serpentinite) and metasomatism of siliceous dolomites. By mass, “pure” steatite is roughly 63.37% silica, 31.88% magnesia, and 4.74% water. It commonly contains minor quantities of other oxides such as CaO or Al2O3.
