Parent Rock - preexisting rock from which metamorphic rocks are formed. •. Methods to classify sedimentary rocks: 1. Texture - the d. metaconglomerate. 7.
Mineralogy - extremely variable, dependent on the original composition of the parent rock; generally contains minerals only formed under high temperature conditions, e.g. andalusite (Al 2 SiO 5 ), cordierite ((Mg, Fe) 2 Al 4 Si 5 O 18 ). Metasedimentary rocks, mostly derived from sandstone and shale, with minor conglomerate and carbonate rock. Includes quartz-rich, mostly nonvolcanic Pinal Schist in southeastern Arizona and variably volcanic-lithic sedimentary rocks in the Yavapai and Tonto Basin supergroups in central Arizona. Metaconglomerate - Parent Rock = conglomerate, pebbles have been flattened Quartzite - fine to medium interlocking quartz grains, Parent Rock = sandstone.
The Rock Cycle . Before moving on to the rest of the course, you should read Interlude C in your textbook (pages 261-268). Now that we have discussed the three types of rocks, it is important to understand how the atoms that make up these rocks cycle through the earth. Overview of metamorphic rocks and their formation. Including explanation of contact and regional metamorphism and the conditions in which they commonly form. Click here for a close up image - #1 . Click here for a close up image - #2.
Phyllite, fine-grained metamorphic rock formed by the reconstitution of fine-grained, parent sedimentary rocks, such as mudstones or shales. Phyllite has a marked fissility (a tendency to split into sheets or slabs) due to the parallel alignment of platy minerals; it may have a sheen on its
Images are Conglomerate is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contain a matrix of finer grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts.
These articles explore rocks of all types—from those you climb to those you collect—and explore how they formed and what they can teach us about the past. These articles explore rocks of all types—from those you climb to those you collect—a
This rock generally has large Metaconglomerate (“Marinace Red Granite”) - another Precambrian-aged polymict metaconglomerate from Brazil.
The metaconglomerates of the Jack Hills of Western Australia are the source rocks for much of the detrital zircons that have been dated to be as old as 4.4 billion years. A conglomerate (sedimentary rock) is the protolith, or parent rock, of a metamorphic rock called a metaconglomerate.

The texture can be foliated or nonfoliated. Foliated metamorphic rock. Foliated metamorphic rocks appeared banded or layered. Foliated rocks can be ordered in terms of increasing metamorphism. In the chart below notice how each of the first three rocks become the parent rock for the next.
What is the parent rock of a Metaconglomerate? Foliated metaconglomerate is created under the same metamorphic conditions that produce slate or phyllite, but with the parent rock (protolith) being conglomerate, rather than clay.

Metaconglomerate - Parent Rock = conglomerate, pebbles have been flattened Quartzite - fine to medium interlocking quartz grains, Parent Rock = sandstone. Marble - fine to medium interlocking calcite crystals, Parent Rock = limestone. Anthracite Coal - Low grade (if T is too high, the coal turns to graphite), Parent Rock = bituminous coal

Click here for a close up image - #2 When rocks are subjected to elevated temperatures and pressures, for example due to deep burial in orogenic (mountain building) zones when two continents collide, they may become metamorphosed (metamorphism is from the Greek, to change in form). 2019-12-02 · Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
