1966年,作者在吉林通化二密铜矿的石英脉晶洞中发现一群罕见的日本双晶石英晶体群。 该日本双晶石英晶体群产于矿区花岗斑岩与石英闪长岩形成的破碎带的石英脉中,脉长30米,厚约1—2米。脉中发现9个残留-溶解型晶洞。日本双晶见于第5号晶洞,洞中共有石英晶体80块,其中就有日本双晶28块。石英晶体间被硅质胶结物、石英碎屑,粒状黄铜矿、方铅矿、闪锌矿、白铁矿、方解石等细粒物所充填。日本双晶呈一对对高矮不一的山
In 1966, the authors discovered a rare group of Japanese double-crystal quartz crystals in the quartz veins of the Tonghua Bismuth Mine in Jilin Province. The Japanese twin quartz crystal group is produced in the quartz vein of the crushed zone formed by granite porphyry and quartz diorite in the mine area. The pulse length is 30 meters and the thickness is about 1-2 meters. Nine residuals were found in the veins - dissolved crystal cave. Japanese twins found in Geode No. 5, a total of 80 quartz crystal hole, of which there are 28 Japanese twins. Quartz crystal between the siliceous cement, quartz debris, granular chalcopyrite, galena, sphalerite, iron ore, calcite and other fine particles filled. Japanese twin was a pair of high and low mountains
