新疆阿舍勒块状铜锌硫化物矿床在阿尔泰克兰海西褶皱带玛尔卡库里深断裂的东北侧,产于中泥盆统阿舍勒组英安岩及英安质火山碎屑岩中,与次火山岩关系密切,矿床具有明显的分带性。矿体下盘矿化和围岩蚀变强烈。认为是与海底火山作用有关的黑矿型块状铜锌硫化物矿床。     

Ecological features of species range formation in the Altai snowcock

Ecological conditions for the Altai snowcock and the history of formation of its range in the Altai-Sayan mountain region are discussed. The range of this species extends mainly over mountain massifs surrounding the Great Lakes Basin in western Mongolia and the Tuva Basin. These regions are characterized by broken relief with steep slopes. Snowcocks populate both humid high-mountain areas of the Alpine type and dry-steppe areas in middle and low mountains. Expansion of this species to the Altai-Sayan region is attributed to Miocene-Pliocene aridization well manifested in central Asia. The recent distribution of the Altai snowcock over different altitudinal belts is explained by alternation of glaciations and interglacial periods in the Pleistocene and anthropogenic impact in the Holocene. The total abundance of this rare species is estimated at 10000–12000 individuals.     

阿尔泰山两河源区生态环境问题研究

由于人类对自然资源的不合理开发利用，以及自然环境的演变，阿尔泰山两河源区的生态环境出现了比较严重的退化。两河源区的生态环境不仅直接关系到阿勒泰地区人民的生活及经济的发展，而且还关系到相关地区的可持续发展问题。针对阿尔泰山两河源区的生态环境问题笔者提出了相应的对策与建议。     

阿舍勒块状铜锌硫化物矿床矿物分带

本文对新疆阿舍勒块状铜锌碱化物矿体的内部构造及矿物共生组合进行了研究,与现代海底硫化物矿床的矿物分带作了比较,初步认为影响该矿床矿物分带的主要因素是成矿溶液的初始温度。     

新疆阿勒泰变质的震旦系及其微古植物群

在阿勒泰地区一些变质地层的多处剖面 近五十个样品中获得了比较丰富的微古植物和少量似几丁虫化石。将此区以往认识不一的哑地层确定为震旦系,并在前人工作基础上进行划分对比,提出了构造运动的新认识。     

赛都金矿成矿地球化学环境

赛都糜棱岩型金矿是阿尔泰地区重要的金矿类型。本文较系统地论述了该类型金矿的成矿物质来源，成矿流体的地球化学，成矿作用过程中的稳定同位素地球化学等成矿地球化学环境，并推测了其成矿时代。     

阿尔泰多拉纳萨依金矿床初探

新疆多拉纳萨依金矿床位于阿尔泰克兰海西褶皱带玛尔卡库里大断裂的西南侧,西与苏联矿区阿尔泰之列宁诺戈尔斯克—孜里亚诺夫斯克构造成矿亚带相接。地层为中泥盆统托克萨雷组浅变质岩,大致呈南北走向的长条状分布在三个斜长花岗岩侵入体之间,并有许多钠长斑岩岩脉穿插。主要构造线方向为北北东,向西倾斜。金矿体赋存在沿断裂带侵入于灰岩中的石英钠长岩(或钠长石化斜长花岗岩)中。蚀变围岩主要为千糜岩化、白云母化的石英钠长岩。石英脉中金的品位虽然较高,但工业储量主要赋存于蚀变围岩中。自然金主要以显微和次显微状独立矿物被包裹于黄铁矿等矿物中,成色很高(932—967),其中的少量元素为银、汞和铋。为与斜长花岗岩有关的岩浆期后高—中温热液充填—交代矿床。

Current State of the Altai Glaciers (Russia) and Trends Over the Period of Instrumental Observations 1952–2008

Results of research into climate and glacier dynamics in the Altai Mountains (Russia) over the period of instrumental observations (1952–2008) are presented in this article. About 1030 glaciers with a total area of 805 km² and volume of 42.5 km³ have been recorded in the Altai Region. The average summer air temperature in different regions of the Altai has increased during the study period from about 0.2°C (Aktru) to 1.1°C (Akkem). The annual atmospheric precipitation rate has also increased, by 8–10%. Since 1952, the glacier area in different regions of the Altai has decreased by 9–27%, and volume by 12–24%. By 2008, as a result of degradation, the total number of glaciers was 953 with an area of 724 km² and volume of 38 km³.     

Structure and formation of conifer stands in the upper timberline ecotone on the North Chuya Ridge,Central Altai

The structure of Siberian stone pine (Pinus sibirica Du Tour.) and Siberian larch (Larix sibirica Ledeb.) stands and specific features of their formation have been studies in the forest-tundra ecotone on the North Chuya Ridge (2235–2475 m a.s.l.). Changes in the structure of these stands along the transition from the upper boundary of closed forests to the high-mountain tundra have proved to have an ambiguous pattern. Both tree species form mixed clusters of similar-aged trees in the lower part of the ecotone but grow singly, in scatters, in its upper part. The formation of conifer stands (tree clusters) in the lower part of the ecotone, on the slopes of the Aktru River valley, began during climate warming in the second half of the 19th century. The expansion of confers to its upper part took place markedly later, in the early 20th century (Siberian larch) or even in the 1930s (Siberian stone pine).
