Features of Hornfels and Soapstone are listed here.The differences between hornfels and soapstone are that soapstone is soft and can be scratched by a fingernail while hornfels is harder and cannot be scratched by a fingernail. Additionally, soapstone is a metamorphic rock that is foliated, while hornfels is also a metamorphic rock but it is unfoliated.Hornfels Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism.Because pressure is not a factor in the formation of hornfels, it lacks the foliation seen in many metamorphic rocks formed under high pressure and ...Table 6.1: Metamorphic rock identification table. 6.2.1 Foliation and Lineation. Foliation is a term used that describes minerals lined up in planes. Certain minerals, most notably the mica group, are mostly thin and planar by default. Foliated rocks typically appear as if the minerals are stacked like pages of a book, thus the use of the term ‘folia’, like a leaf.Hornfels is a metamorphic rock formed when magma heats and recrystallizes the original rock. Pressure is not a factor in its formation. The name "hornfels" means "hornstone" in German, referring to the way the rock's texture and toughness resemble animal horn. The colors of hornfels are as variable as the source rock used to produce it.Know all about Hornfels and Soapstone Properties here.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. 7.4.1 Hornfels. Hornfels is medium-to-coarse crystalline metamorphic rocks formed out of contact metamorphism, dark color, and rich in silicates with granoblastic and porphyroblastic texture. They consist of andalusite, garnet, and cordierite as major minerals and quartz, feldspar, biotite, muscovite, and pyroxene as a characteristic mineral.Hornfels is a tough, fine-grained rock that is made by contact metamorphism where magma bakes and recrystallizes the surrounding rocks. ...
