As nouns the difference between metamorphic and hornfels is that metamorphic is (mineralogy) a rock that has been changed from its original form by subjection to heat and/or pressure while hornfels is any of a series of contact metamorphic rocks that have been baked and indurated by the heat of intrusive igneous masses and rendered massive, hard, splintery, and in some …
14/19 Correct In general, quartzite is one color, whereas gneiss has a striped, two-colored barcode appearance. Lab Activity 7.4.2 - The Differences between Igneous, Sedimentary, and Metamorphic Rocks By this point, you have studied igneous, sedimentary, and metamorphic rocks. It is a low-grade metamorphic rock that splits into thin pieces. Soapstone. metamorphic rock that consists primarily of talc with varying amounts of other minerals such as micas, chlorite, amphiboles, pyroxenes, and carbonates. It is a soft, dense, heat-resistant rock that has a high specific heat capacity.Crystals in hornfels grow smaller with metamorphism, and become so small that specialized study is required to identify them. These are common around intrusive igneous bodies and are hard to identify. The protolith of hornfels can be even harder to distinguish, which can be anything from mudstone to basalt. Figure 6.18: Macro view of quartzite.The dark-coloured sedimentary rocks next to this granite contact (shown in the 3D model below) have been heated and transformed into hornfels. The original layering in the sedimentary rocks no longer visible. There is a thin zone on the edge of the granite with small crystals where the granite has cooled rapidly. This is called a chilled margin. The streak of Soapstone is black while that of Hornfels is unknown. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Soapstone is heat resistant, pressure ...
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? All of the rocks called hornfels—a hard, fine-grained, flinty rock—are created when heat and fluids from the igneous intrusion alter the surrounding rock, changing ... quartzite, hornfels, marble.

The original layering in the sedimentary rocks no longer visible. There is a thin zone on the edge of the granite with small crystals where the granite has cooled rapidly. This is called a chilled margin. Soapstone. Soapstone is one of the softer minerals due to its high talc content, and can scratch leaving a white residue on the surface. Its hardness ranges between 1 and 2 ½ on the Mohs scale, and it is recognised for its soapy texture. Soapstone carvings are generally less expensive, but are equally admired for their fine and quality carving.Which rock? Rocks are made of minerals.
