大山火山锥幔源包体与寄主岩成因分析

认为大山火山锥由过碱性霞石岩组成，其中含尖晶石二辉橄榄岩包体和捕虏晶；包体与寄主岩共存，但二者无成因联系；寄主岩是石榴石二辉橄榄岩部分熔融的产物，形成深度在７５ｋｍ以下；包体则是５０ｋｍ深处富化地幔岩石碎块及其解离的产物。这一结论对建立渤海裂谷区的上地幔剖面具重要意义。

马氏珠母贝外套膜组织培养的条件和方法初探

经过反复试验，筛选出适宜于马氏珠母贝外套组织培养的平衡盐溶液（改进的ＭＭＢＳＳ）、基本培养基；确立了防止污染的组织净化方法，并筛选出一种能促进细胞生长的贴壁物质（ＳＭ）。其主要培养方法为：用合抗生素的改进ＭＭＢＳＳ（青霉素２０００Ｕ／ｍｌ，链霉素２５００Ｕ／ｍｌ）洗涤１０次，再用不含抗生素的改进ＭＭＢＳＳ清洗５次，将组织切成３ｍｍ×３ｍｍ的小块，贴于含０．５％ＳＭ的培养瓶底，加入改进的贝培养基，在２０℃，ｐＨ６．８条件下培养。经这种条件和方法培养的马氏珠母贝外套膜组织，４小时细胞开始游离，３天游离出来的细胞铺满瓶底，４天细胞分泌珍珠质．培养７天大量的成纤维细胞出现，细胞培养能持续数十天。     

布格重力异常的“深化”解释

文章对跨越大足重力高和龙门山褶皱带的重庆－黑水重力剖面作了解释。解释时根据深地震测深和面波频散层析成像的结果，用二维模型进行正演拟合。根据计算结果得出：在作区域重力异常解释时，除要考虑莫霍面及其以上各密度层的影响外，尚应考虑上地幔顶部的密度变化。     

Trace-element of Tuoyun clinopyroxene: Implication for the deep processes of lithospheric mantle beneath the southwest Tianshan, West China

Based on the LAM-ICPMS analytic results on the trace elements of clinopyroxenes in peridotitic xenoliths occurring in early-Cretaceous basalts from western Xinjiang, the properties and the deep processes, including partial melting and mantle metasomatism, of the subcontinental lithospheric mantle beneath the Tuoyun Basin are analyzed. In the northern edge of the Tarim Basin (southwest Tianshan), the Mesozoic subcontinental lithosphere which has experienced the effect of partial melting (<10%) and intricate mantle metasomatism is characterized by Phanerozoic ‘ocean-type’ mantle. The superposed influence of SiO₂-unsaturated silicate melt and carbonate melt probably results in the metasomatic medium which resembles the hydrous silicated carbonate melt in some aspects. By comparing Tuoyun mantle with Cenozoic main mantle beneath eastern China, the properties are similar, while the former shows finer grain and higher diopside content of the peridotites and more conspicuous modal metasomatism.     

Mantle metasomatism by P- and F-rich melt/fluids: evidence from phosphate glass in spinel lherzolite xenolith in Keluo, Heilongjiang Province

Spinel lherzolite xenoliths were found in phonolitic alkaline basalt in the Keluo area, Heilongjiang Province. Detailed electron-microprobe study revealed abundant phosphates and associated metasomatic minerals between primary phases in xenolith. The phosphates are considered special residual phases (coagulation) of P- and F-rich mantle melt/fluid, most of which were identified as glass phases based on Raman spectroscopic analyses. Such melt/fluid also further metasomatized primary minerals, thus leading to formation of reaction rims successively composed of Cr-spinel symplectitic zone and olivine diopside zone. Therefore, the P- and F-rich melt/fluid played an important role in the upper-mantle metasomatism in the Keluo area. It is suggested that this kind of metasomstism may occur in some other places of eastern China. The present results may also have significance in study-ing types of metasomatic melt/fluid and its evolution in the lithospheric mantle beneath eastern China.
