  meteoric origin
The nonstationary process of the accumulation of ions of meteoric origin, which is caused by propagation of planetary waves at altitudes of the lower ionosphere, is considered.
      
It is shown that the action of planetary waves on ions of meteoric origin is a necessary element in the scheme of the occurrence of midlatitude sporadic layers.
      
Strontium isotopes also point to a meteoric origin of diagenetic fluids.
      
On the other hand, as indicated by fluid inclusion data, the ore-forming fluid at the second stage was of meteoric origin and the precipitation of gold was caused by phase separation.
      
Acidic hydrothermal solutions either of magmatic or of meteoric origin reacted with the upper tectonically fractured parts of the Florina granite and became enriched in iron, thorium, uranium, zircon and rare-earth elements.

From a systematic analysis of the whole history of the protoplanetary cloud and the observational facts of the Earth's atmosphere, we propose a new theory on the Origin of the atmospheres of the Earth and the planets. For the Earth-like planets, there were profound primordial atmospheres originated from the protoplanetary cloud by the accretion of the embryoes of planets. These primordial atmospheres has existed in a time scale of 10~8—10~7 years and were composite from chemically reducing gases. The presence...

From a systematic analysis of the whole history of the protoplanetary cloud and the observational facts of the Earth's atmosphere, we propose a new theory on the Origin of the atmospheres of the Earth and the planets. For the Earth-like planets, there were profound primordial atmospheres originated from the protoplanetary cloud by the accretion of the embryoes of planets. These primordial atmospheres has existed in a time scale of 10~8—10~7 years and were composite from chemically reducing gases. The presence of such a reducing atmosphere may be of great significance to the theories of cosmogony and the origin of life. The contents are as follows 1. The escape of the nebulae and the planetary atmosphers. 2. The blowing-off of the atmospheres and the dissipation of gases driven by the solar wind. 3. The accretion of gases by the planetary embryoes. 4. The primordial atmospheres.

在比较系统地分析了原始太阳星云气体演化全过程和地球与行星大气观测事实的基础上,本文讨论了地球与行星大气起源;地球应有一初级原始大气阶段,其主要特征是还原志。文中还求得了初级原始大气的上下限,讨论了这一大气的性质与演化。

Based on the work of hydrogeological survey in the Chongli montainous area (1:200000), the authors have prbliminarily carried out a discssion on the formatinnal mechanism of the chemical composition of groundwatre and the stage of lixiviation by studying the geochemical regularity of groundwater, the hydrogeologichl condition and the history of geological development. The study shows that the groundwater in this area belongs to atmogenic lixiviation-infiltration water, and lixiviation is the essential action...

Based on the work of hydrogeological survey in the Chongli montainous area (1:200000), the authors have prbliminarily carried out a discssion on the formatinnal mechanism of the chemical composition of groundwatre and the stage of lixiviation by studying the geochemical regularity of groundwater, the hydrogeologichl condition and the history of geological development. The study shows that the groundwater in this area belongs to atmogenic lixiviation-infiltration water, and lixiviation is the essential action of the formation of the chemical composition,but the exchange adsorption of anions and the mixing action are also responsible for it to some extent. The lixiviation is in sulfate-carbonate stage.

笔者在进行崇礼山区1/20万水文地质测绘工作基础上,通过研究地区地下水的地球化学规律性,并结合区域水文地质条件与地质发展历史,对地下水化学成分的形成机理以及岩石的溶滤阶段进行了初步的探讨,认为本区地下水属大气起源的溶滤──渗入成因水,溶滤作用为其化学成分形成的基本作用,阳离子吸附作用与混合作用在一定程度上也影响着地下水化学成分的形成;溶滤咋用发育不完全,岩石溶滤处于硫酸盐—碳酸盐过渡阶段。
