Gw mau tau Pasipatan fisik dari Mineral. Jelasin dalam bahasa sunda

Klasifikasi mineral bisa dibasajankeun, bisa ogé pajeujeut. Mineral bisa dicirikeun dumasar sababaraha pasipatan fisik, di antarana cukup sampurna pikeun idéntifikasi tanpa ayana equivocation. Dina kasus séjén, mineral ngan bisa diklasifikasikeun ku analisis kimia atawa difraksi sinar-X nu leuwih pajeulit; hanjakal, métode ieu kadang méakkeun béaya jeung waktu nu teu saeutik, jaba bisa ngaruksak sampelna deuih.

Pasipatan fisik nu ilahar dipaké nyaéta:

Struktur jeung watek kristal: See the above discussion of crystal structure. A mineral may show good crystal habit or form, or it may be massive, granular or compact with only microscopically visible crystals.

Teuasna: the physical hardness of a mineral is usually méasured according to the Mohs scale of mineral hardness.

Luster indicates the way a mineral's surface interacts with light and can range from dull to glassy (vitréous).

Warna indicates the appéarance of the mineral in reflected light or transmitted light for translucent minerals (i.e. what it looks like to the naked eye).

Streak refers to the color of the powder a mineral léaves after rubbing it on an unglazed porcelain streak plate.

Cleavage describes the way a mineral may come apart or cléave in different ways. In thin section, cléavage is visible as thin parallel lines across a mineral.

Fracture describes how a mineral bréaks when broken contrary to its natural cléavage planes.

Specific gravity relates the mineral mass to the mass of an equal volume of water, namely the density of the material.

Pasipatan séjén: fluorescence (response to ultraviolet light), magnetism, radioactivity, tenacity (response to mechanical induced changes of shape or form), and réactivity to dilute acids.
