摘要
对湘南多金属成矿区方解石的研究表明，产于钨矿床中的方解石以层状晶体发育为特征，晶体形态主要为｛０００１｝和｛０１２｝＋｛１０１０｝，晶体表面具有菱形生长阶梯；产于铅锌矿床中的方解石一般不出现层解石，晶体形态主要为｛２１３１｝，｛０１１２｝＋｛１０１０｝和｛０００１｝＋｛１０１０｝＋｛０１１２｝，晶体表面平行纹发育；远矿正常灰岩内方解石晶体形态主要为｛４０４１｝。
Study on forms and surface microstructure of calcite crystals which occur in polymetallic deposits in Southern Hunan shows that the calcites in Yaogangxian tungsten deposit have a tendency to develop into layer crystals and posses rhomboidal growth steps;the crystals are usually in {0001} and+forms and those in country rock,in and,and that ealcites in Pb-Zn deposit have concentrated parallel lines on the surfaces of crystals;the crystals are generally in,+and ++forms etc;the crystal in recrystallized limestone near the ore body are in +and forms; amdthose in the limestone far trom the ore body in.
