Examples of ferromagnesian silicate
http://itc.gsw.edu/faculty/tweiland/Minlect.htm WebThe oxidation of the iron in a ferromagnesian silicate starts with the dissolution of the iron. For olivine, the process looks like this, where olivine in the presence of carbonic acid is converted to dissolved iron, carbonate, and silicic acid: ... One example of that is the Mt. Washington Mine near Courtenay on Vancouver Island (Figure 5.2.3 ...

WebMinerals of the amphibole group are double-chain ferromagnesian silicates; examples of amphibole group minerals include grunerite (Fe 7 Si 8 O 22 (OH) 2) and tremolite (Ca 2 Mg 5 Si 8 O 22 (OH) 2). The same cations (such as calcium and sodium) are present in both groups, but the hydroxyl anion is characteristic of amphiboles. WebThe term siliciclastic refers to sediments composed mostly of silicate minerals. The most common sedimentary rocks – including shale, sandstone, and conglomerate – form from siliciclastic sediments. Other kinds of sedimentary rocks consist of carbonates (in limestones), iron oxides and hydroxides (such as hematite or goethite in iron formation), …
