青藏高原冬小麦田辐射能量收支的初步研究

通过对青藏高原冬小麦田净全辐射各分量的观测资料分析，论述了净全辐射及其各分量的日变化特征；计算得出冬小麦抽穗—乳熟期麦田平均反射率为13.3%，净全辐射占总辐射百分率:白天75%，包括夜间67.4%；指出了净全辐射和总辐射间存在良好的线性关系，给出了由总辐射计算净全辐射的经验公式。

西藏东部南迦巴瓦地区变质作用特征

西藏东部的南迦巴瓦地区包括喜马拉雅地体、中缅地块和印度河－雅鲁藏布江缝合带的一部分。根据区内构造特点、变质岩共生组合、时空分布、矿物共生组合及其反应关系的研究，揭示了本区变质作用特征。南迦巴瓦群发育了一套较完整的递增变质带，经历了先升压后升温的演化过程；雅鲁藏布江变质岩带经历了一次高压低温变质作用；帕隆群变质作用为一个先升温后升压，温压同时达到高峰的演化过程。     

吉林东南部早寒武含铜层及其形成的古地理分析

吉林省东南部早寒武世晚期地层中含有数层含铜层，它们主要赋存在红色岩层所夹的灰绿黄绿色岩层之中。本区含铜层的形成与当时富氧阶段中的缺氧时期息息相关；而且该类型含铜层主要产自滨海或滨浅海地带，受当时古地理严格控制     

西藏羌塘地区几个地质构造问题

提出了西藏羌塘地区的六个地质构造问题。包括冈瓦纳与欧亚大陆古特提斯界线；羌塘地区是否存在加里东期或更古老基底；羌塘地区的地层系统及其对比；狮头山、黑熊山一带蓝片岩的地球动力学意义；龙木错─双湖蛇绿岩的性质、成因及年代；羌塘盆地中三叠世以前是一个统一的盆地还是分属两大陆的边缘海盆等。这些问题的解决将有助于更加清楚、完整地认识青藏高原的地质历史过程。     

Stratigraphy of the upper cretaceous and lower tertiary strata in the Tethyan Himalayas of Tibet (Tingri area,China)

The 1500-m-thick marine strata of the Tethys Himalaya of the Zhepure Mountain (Tingri, Tibet) comprise the Upper Albian to Eocene and represent the sedimentary development of the passive northern continental margin of the Indian plate. Investigations of foraminifera have led to a detailed biozonation which is compared with the west Tethyan record. Five stratigraphic units can be distinguished: The Gamba group (Upper Albian - Lower Santonian) represents the development from a basin and slope to an outer-shelf environment. In the following Zhepure Shanbei formation (Lower Santonian - Middle Maastrichtian), outer-shelf deposits continue. Pebbles in the top layers point to beginning redeposition on a continental slope. Intensified redeposition continues within the Zhepure Shanpo formation (Middle Maastrichtian - Lower Paleocene). The series is capped by sandstones of the Jidula formation (Danian) deposited from a seaward prograding delta plain. The overall succession of these units represents a sea-level high at the Cenomanian/Turonian boundary followed, from the Turonian to Danian, by an overall shallowing-upward megasequence. This is followed by a final transgression — regression cycle during the Paleocene and Eocene, documented in the Zhepure Shan formation (?Upper Danian - Lutetian) and by Upper Eocene continental deposits. The section represents the narrowing and closure of the Tethys as a result of the convergence between northward-drifting India and Eurasia. The plate collision started in the Lower Maastrichtian and caused rapid changes in sedimentation patterns affected by tectonic subsidence and uplift. Stronger subsidence and deposition took place from the Middle Maastrichtian to the Lower Paleocene. The final closure of remnant Tethys in the Tingri area took place in the Lutetian.

西藏措勤地区石炭纪—早二叠世古地理演化

措勤地区在泥盆纪浅海碳酸盐台地的背景基础上,在石炭纪—早二叠世发育了一套陆源碎屑为主的海相沉积,古地理呈北部以陆棚海为主、南部发育斜坡-深海相的特征。早石炭世永珠组陆棚浅海限于北部的甲龙到阿布勒一带,其南侧至格嘎一措勤一线发育较宽的斜坡相沉积,晚石炭世时发生海侵,并随着冰期气候的盛行在边缘斜坡海环境内沉积了多套冰海砾岩,随着冰期气候的结束和海退,早二叠世昂杰组陆棚海沉积范围向南扩展到格嘎-达雄南部,陆棚海地边缘发育了生物礁或生物滩。古地理演化反映了研究区在早石炭世受南北向拉张的构造背景下形成了不同于泥盆纪碳酸盐台地的陆棚海—斜坡—深海盆地的古地理格局,晚石炭世拉张达到鼎盛,其后的早二叠世主要发育了稳定陆棚海沉积。
