Correct! For the last one, this was what I have in my binder:1. Why are diamond and graphite different minerals if they're both made of carbon? 2. What's the name origin of Aragonite? 3. What is the difference between cleavage and fracture? 4. What type of minerals exhibit hackly fracture? Give 2 examples. 5. Give 3 examples of epigenetic changes and define them.1. Diamond and Graphite are different allotropes of carbon. 2. It comes from Molina de Aragon, Spain. 3. Cleavage is the breaking of minerals along planes with weak bonding zones. Fracture is the breaking of minerals without a definite shape. 4. Copper, Silver 5. Not sure....?
Epigenetic change (secondary processes) may be arranged under a number of headings, each of which is typical of a group of rocks or rock-forming minerals, though usually more than one of these alterations will be found in progress in the same rock. Silicification, the replacement of the minerals by crystalline or crypto-crystalline silica, is most common in felsic rocks, such as rhyolite, but is also found in serpentine, etc. Kaolinization is the decomposition of the feldspars, which are the most common minerals in igneous rocks, into kaolin (along with quartz and other clay minerals); it is best shown by granites and syenites. Serpentinization is the alteration of olivine to serpentine (with magnetite); it is typical of peridotites, but occurs in most of the mafic rocks. In uralitization, secondary hornblende replaces augite; chloritization is the alteration of augite (biotite or hornblende) to chlorite, and is seen in many diabases, diorites and greenstones. Epidotization occurs also in rocks of this group, and consists in the development of epidote from biotite, hornblende, augite or plagioclase feldspar.
