Some foliated rocks are also banded. Banding means that the rock consists of alternating, thin layers (typically 1 mm to 1 cm) of two different mineral compositions. Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Due to geological changes, a metamorphic rock of the foliated or nonfoliated type will be created. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth's crust. Geologic and U–Pb geochronologic studies in this area reveal a coherent but deformed and metamorphosed sequence of rocks belonging to the Yukon–Tanana terrane, including pre-mid-Paleozoic marble, schist, and quartzite, mid-Paleozoic orthogneiss and metavolcanic rocks, and upper Paleozoic metaconglomerate and metavolcanic rocks. Becoming a parent enters you into a completely new and sometimes overwhelming world.

Produced by platy minerals growing in direction of least stress. • Nonfoliated - typical when parent rock is sandstone or limestone. Also occurs in contact metamorphism and … 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 www.gvsuhsag.weebly.com 6 Non Foliated NA quartz rock fragments Conglomerate Metaconglomerate 7 from SCI 0900 at Liberty University Online Academy Metamorphic Rocks.
