E35.3629 Gawo Lopyapyala Lokonzekera

CNOPTEC ndi mtundu wathu wa ma labotale apamwamba, polarizing, metallurgical, fluorescence microscope mumsika waku China, tsopano tikugwiritsa ntchito chizindikirochi mumsika wapadziko lonse kuyambira 2018.

Thanthwe limapangidwa ndi mchere umodzi kapena zingapo ndi galasi lachilengedwe, gulu lolimba lokhazikika. Miyala yopangidwa ndi mchere umodzi amatchedwa miyala ya mono-ore, monga marble wopangidwa ndi calcite, quartzite wopangidwa ndi quartz, ndi zina; miyala yopangidwa ndi michere ingapo amatchedwa thanthwe lophatikizika, monga granite wopangidwa ndi mchere monga quartz, feldspar ndi mica Composition, gabbro imapangidwa ndi plagioclase ndi pyroxene, etc. Madzi omwe alibe mawonekedwe ena, monga mafuta, mpweya monga gasi lachilengedwe, ndi mchenga wosasunthika ndi matope, si miyala.

Thanthwe ndi chimodzi mwazinthu zomwe zimapanga kutumphuka kwa dziko lapansi ndipo ndiye gawo lalikulu la lithosphere yapadziko lapansi. Zina mwa izo, feldspar ndi gawo lofunika kwambiri pakupanga miyala mu kutumphuka, ndi gawo la 60% [2], ndipo quartz ndiye miyala yachiwiri yochuluka kwambiri.
Miyala imagawidwa molingana ndi chibadwa chawo, kapangidwe kake ndi kapangidwe ka mankhwala. Miyala yambiri imakhala ndi silika (SiO2), pomwe 74.3% ya kutumphuka kwake ndikotsiriza. Zomwe zili pakachitsulo m'thanthwe ndi chimodzi mwazinthu zofunika kuzindikiritsa zomwe zili pamwalawo [3].
Miyala ndi gwero lofunikira lazida zoyambira anthu ndipo ili ndi tanthauzo lofunikira mu evo ya anthu
