主碰撞期成矿,mineralization movements during main Indian-Asian collision period
main Indian-Asian collision period主碰撞期
1.There are mineralization movements duringmain Indian-Asian collision period (41~65 Ma)in the Gangdese belt, which means a lot for the mineral resource prospecting of this area.6Ma之间,属于燕山晚期;②亚贵拉铅锌、钼矿矿床属于斑岩型钼矿矽卡岩型-热液脉型铅锌铜银多金属矿床,而非晚石炭世—早二叠世的海底喷流沉积成因矿床;③亚贵拉-沙让矿集区矿床的形成得益于燕山晚期和喜马拉雅早期的岩体侵位,并与碰撞前(180～65Ma)及主碰撞期(65～41Ma)的岩浆活动关系密切,属于碰撞前和主碰撞期早期成矿。

5)main metallogenic age主成矿期
1.The comprehensive study of distribution of placer gold, intersection of one rock/ore vein system with another, and isotopic age determination for ores, reveals that themain metallogenic ageof Au, Ag deposits in the area is the late Yanshanian period.本文通过对砂金分布、岩矿脉体穿插关系以及矿石同位素测年结果等实际资料的综合研究分析，证明本区金银矿床的主成矿期应为燕山晚期；同时归纳出区内各类金属矿产在时间演化上具有长期性、多期性、阶段性、序列性、继承性诸项规律。

元张成造栀子纹剔红盘中国元代漆器。高2.6厘米，口径 16.5厘米。圆形，栀子纹肥腴圆润，布满全盘，空隙无多，只于深处见黄色漆地，是《髹饰录》所谓"繁文素地"的雕法。背面雕香草纹，峻深而圆转自如。足内有"张成造"针划款。现藏故宫博物院(见图)。张成是元末嘉兴西塘杨汇的雕漆巨匠，与同里的杨茂齐名，但从传世实物来看，技艺似在杨茂之上。
