摘要
秦岭泥盆系中广泛发育一套与成矿有关的热水沉积岩，其主要矿物成分为钠长石、石英、含铁白云石、电气石及重晶石等。本文主要是通过不同方法来研究各种矿物的标型特征，这些特征均反映了矿物及其所赋存的岩石和矿床是由热水沉积作用形成的，并为进一步研究热水沉积岩和热水成矿作用提供了重要的矿物学依据。
In strata-bound lead-zinc and gold deposits of the Qinling Devonian system there exists a vari-ety of hot-water sedimentary rocks associated with mineralization, including silicilith, albitite andbaritic rock which consist of albite, quartz, ferruginous dolomite, tourmaline, barite, etc.The typomorphic characteristics of the above-mentioned minerals have been studied. These ty-pomorphic characteristics are full proof that these minerals and relevant rocks and deposits are ofhot-water sedimentary origin. This study provides mineralogical evidence for hot-water sedimenta-ry rocks and hot-water deposits.
