Deep source gas refers to inorganic genetic gas or abiogenic gas which comes from deep crust or upper mantle, and has apparent geology and geochemistry characteristics. 深源氣是指來(lái)自地殼深部或上地幔的無(wú)機成因天然氣或稱(chēng)非生物成因天然氣，它具有明顯的地質(zhì)地球化學(xué)特征。
Geochemical studies show that magma of these two series originated from the same impoverished mantle source, with the source rock being spinel peridotite. 地球化學(xué)研究證明，這兩個(gè)系列的巖漿起源于同一貧化型地幔源區，源巖類(lèi)型為尖晶石橄欖巖。
