Sanidinite (some have transformed to perthite) and quartz inclusions with radial cracks are often seen in the garnet of eclogite. The geothermal gradient of ＜10℃/km is recorded in the early stage mineral assemblage of high-pressure metapelitic rocks with relict aragonite. these features imply a possibility that there may be ultra-high-pressure rocks existed in Altun.

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

The suppressing effect of BJ fly ash on ASR expansion of siliceous gravel, zeolitic perlite and silica glass in 1M NaOH solution were studied at 40℃, 60℃ and 80℃ respectively. It is indicted that the suppressing effect of one certain fly ash on ASR expansion various with temperature and the reactivity of aggregate.

通过BJ粉煤灰在40℃、60℃、80℃的1M NaOH溶液中对硅质砾石、沸石化珍珠岩和石英玻璃ASR膨胀抑制效果的研究，发现同种粉煤灰在不同温度下对ASR膨胀抑制效果随温度和集料种类而异。

The ASR features of mortars with siliceous gravel. zeolitic perlite and silica glass storage at various conditions were examined by SEM/EDS. It was found that ASR had taken place seriously even with high replacement of cement by PFA.

采用SEM／EDS研究了石英玻璃、硅质砾石和沸石化珍珠岩在不同养护条件下ASR特征，发现掺加粉煤灰，甚至大量粉煤灰后，集料仍发生了的反应，有时反应还很严重。

The experimental products include crystal phase quartz, feldspar (alkila-feldspar, albite, K-feldspar), zinnwaldite and topaz, a melt phase and a trace vapour. The solid products were been studied by optics method, electron microprobe and X-ray analysis. The results show that liquidus temperature raises slightly and solidus temperature falls down obviously and that the upper temperature limit raises for the stability field of quartz and topaz, and falls down for the stability field of alkila-feldspar as F contents in crease.

实验淬火产物包括结晶相石英，长石(碱性长石，钠长石、钾长石)，铁锂云母和黄玉及玻璃相和微量流体，对固相淬火产物进行了系统和详细的显微观察及电子探针和x射线分析，研究了F对钠长花岗岩液、固相线温度、相关系和相组合的影响和含F钠长花岗岩的结晶序列和熔体演化、F在流体和熔体之间的分配及F对花岗质熔体结构的影响，对含黄玉矿物组合进行了一系列热力学矿物平衡计算，获得如下重要结论
