K—Na—Ca温度计在一些矿床的成矿温度研究中的应用效果

K—Na—Ca温度计是利用矿物包裹体成分中钾、钠、钙的摩尔浓度,使用已有公式计算成矿温度的一种方法。通过在一些矿床中的应用效果表明,用该温度计计算的温度与矿床产出地质条件相符,并与用其他方法测得的温度基本一致,可以代表成矿温度。此外该温度计与压力无关;不受矿物透明度和介质临界条件限制,其应用范围较其他测温方法的要广。     

汪民在全国地质勘查管理座谈会上指出矿业权管理要依法予以规范

The Geologic Time Scale and the Italian stratigraphic record

The construction of the Geologic Time Scale (GTS) is a titanic scientific challenge that has been under way for two centuries and will require much dedicated effort in the future. Italy preserves a paramount stratigraphic record of Mesozoic and Cenozoic marine sediments that have been significant in the development of the modern GTS. The Italian stratigraphic record has been histori-cally important in introducing and defining the standard Chronostratigraphic Units (CUs) of the Neogene and Quaternary. Pelagic successions from Northern Apen-nines and Southern Alps have been used in the seventies for integrating the late Cretaceous-Paleogene Geomag-netic Polarity Time Scale (GPTS) with planktonic microfossil biostratieraohv and standard CUs. This was a major contribution to the construction of a new gener-ation of GTS based on integrated magnetobiochronol-ogy. The middle Miocene to early Pleistocene marinerecord from Sicily and southern Italy has been funda-mental for establishing the recently developed Astro-nomical Time Scale (ATS). In prospect, there are many potentials still to be exploited in the Italian marine stratigraphic record for implementing the GTS by defin-ing GSSPs of various CUs, improving magneto-biochronology and extending downwards the ATS.

中央投20亿元启动地质勘查基金——着重用于重点矿种、重点成矿区带的前期勘查

为了加大国家财政对矿产资源勘查投入力度，鼓励和引导社会资金投入，建立矿产资源勘查投入良性循环机制，财政部、国土资源部近日发布《中央地质勘查基金（周转金）管理暂行办法》。这是贯彻落实《国务院关于加强地质工作的决定》的第一个配套文件。     

庆祝中国共产党建党八十五周年——山东省地质科学研究院“七一”活动纪实

近期，山东省地质科学研究院为庆祝中国共产党建党85周年开展了一系列丰富多彩的纪念活动。6月29日，组织全院党员、团员到莱芜战役纪念馆学习参观，缅怀了革命先烈的丰功伟绩，游览了溪水潺潺、层峦叠翠的“九龙大峡谷”。7月1日，全院隆重召开了庆祝中国共产党建党85周年大会暨“树立社会主义荣辱观”演讲交流会。院党委书记、院长王君仁作了重要讲话。来自院属各单位的14位代表围绕“学党章、知荣辱”主题，联系实际畅谈了学习体会和收获。该次学习活动对全院干部职工树立“八荣八耻”道德观，推动全院精神文明建设起到了积极的作用。     

The Lagoon of Venice： geological setting,evolution and land subsidence

The paper deals with the geological setting, history and subsidence of the Venetian Plain. Major attention is paid to the Pleistocene-Holocene stratigraphic sequence in the Lagoon of Venice, in relation to its origin that datesback to 6-7 kyr BP. Geological land subsidence, which played an important role in the origin and the evolution of the lagoon, and anthropogenic subsidence, that has recently assumed a major importance for the Venetian environment, are discussed. Considering also the sealevel rise, 23 cm loss in land elevation has occurred in the last century, leading to increased flooding events and environmental problems that require protective works.
