青海滩间山金矿床找矿矿物学研究

本文重点讨论了滩间山金矿床主要矿石矿物的标型特征及其地质意义,可用于矿床类比及该类型金矿床的找矿评价和预测。     

青海区调工作发展意向

本文认为,青海区调工作在今后相当长一段时间内,仍将以外业为工作主体。区调中应强化找矿意识。在交通不便、高寒缺氧、外业时间短的青藏高原,在学习应用新理论、新方法的同时,加强遥感地质工作、运动新的信息化工作手段,很有必要。     

唐古拉山中段开心岭群乌丽群的时代定义问题

根据最新区域地质调查的代表剖面,在分析研究下二叠统开心岭群、上二叠统乌丽群的岩性组合特征、沉积类型、古生物面貌的基础上,将二叠系建立5个岩石地层单位和相应的5个生物地层单位,代表栖霞期—长兴期地层层序与生物序列;区内生物性质属特提斯动物群和华夏植物群;青南乌丽与藏北双湖及昌都妥坝属同一含煤建造,成煤期为龙潭中期—长兴期。     

视磁化强度反演的基本原理及应用实例

本文围绕视磁化强度反演问题,着重对正则化滤波器的选择、截止频率的确定、平均深度的确定、反演解的改善等问题进行了讨论。最后,以民和盆地两条剖面为例,反演了视磁化强度,结合磁化率资料,对盆地基底岩性进行了划分。     

Upgrade Procedure for the Delingha 13.7-m Telescope

The 13.7-m millimeter-wave radio telescope of Purple Mountain Observatory operates at 3200-m above the sea level near Delingha, Qinghai Province, China. Equipped with a superconducting SIS receiver, the telescope is used in the millimeter-wave band ranging from 85 to 115 GHz. An upgrade procedure is reported here which includes a superconducting SIS receiver, a new phase-locked local oscillator, a dedicated multi-line backend system, and a new control system based on industrial computer with PCI bus. With the dedicated multi-line backend system, the CO and isotopic lines around 110 GHz are obtained simultaneously. In recent years, scientific activities with this telescope have been focused on studies of Galactic molecular clouds and star formation regions, including surveys of molecular lines from IRAS sources and large-scale map of molecular clouds. Other programs include studies of the circumstellar envelope of late-type stars and interaction of Galactic supernova remnants with dense molecular gas.     

青海德尔尼硫化物矿床成因的新认识

通过对青海德尔尼硫化物矿床的产出部位、成矿环境、矿石矿物的组合、主要化学元素的成份及同位素测试数据等分析研究,认为该矿床具有裂谷成矿机制的特征,成因类型应属裂谷型层控矿床。     

依法征地保障用地确保全省通县油路建设实施

征地工作事关经济建设,涉及农民群众的切身利益和社会稳定,近年来,随着我省基础设施建设项目增加,征地数量也相应增加,因征地而引发的矛盾越来越多。 西部地区县县通油路工程在我省实施后,国资源管理部门在政府的统一领导下,在时间紧、任务重、难度大的情况下,严格按照国土资源部《征用土地公告办法》和《关于切实维护被
