A breach is material if, as a result of the breaching partyâs failure to perform some aspect of the contract, the other party receives something substantially different from what the contract specified.
In mineralogy, crystal habit is the characteristic external shape of an individual crystal or groups of crystals. A single crystal's habit is a description of its general shape and its crystallographic forms, plus how well developed each are.Recognizing the habit may help in identifying a mineral.or example, minerals used for asbestos insulation often grow in a fibrous habit, a mass of very fine fibers. The terms used by mineralogists to report crystal habits describe the typical appearance of an ideal mineral.
igneous rock containing 56â65 percent silica. This category includes primarily feldspathic rocks with small admixtures of such ferromagnesian minerals as pyroxene, hornblende, and, more rarely, biotite. Intermediate plagioclases (oligoclase, andesine) are typical of feldspars.According to the weight percentage of the constituents of intermediate rocks, a distinction is made between the sodium series (diorites, andesites, andÃ©sites) porphyrites and the calcic (series, syenites). trachytesntermediate rocks are found mainly among extrusive rocks in which andesites andÃ©sites and porphyrites predominate over trachytes and; porphyries the intrusive (rocks, diorite) syenite are much less widely. distributed
