1951年，在蒙古农业综合考察队之下成立了戈壁地质分队，其任务是对尚未进行过地质研究的后阿尔泰戈壁地区进行踏勘。分队成员包括地质矿物学博士В. М. 西尼岑和列宁格勒矿业学院的毕业班学生В. А. 阿曼托夫。\n在乌兰巴托市，分队补充了汽车司机А. С. 卡拉宾、翻译——蒙古国立大学三年级学生达什齐克·桑布耶夫以及工人扎纳。6月10日，分队乘分配给他们的ЗИС-5型汽车，沿古老的戈壁之路，经达兰扎尔嘎朗和奥博图胡拉尔，驶离乌兰巴托前往研究区域。\n后阿尔泰戈壁构成蒙古人民共和国的西南部分，是其距离首都最遥远的地区。进入后阿尔泰戈壁有两条路径：一是经车车尔勒格大道，穿越杭爱山脉、湖泊谷地、蒙古阿尔泰山；另一条是经达兰扎尔嘎朗大道，沿戈壁高原延伸，仅穿越阿尔泰山支脉。\n第一条路通向后阿尔泰戈壁的西北部，第二条则通向其东南部。从乌兰巴托到该区域最近点（从任一方算起）的距离大致相同，约为1300—1350公里。\n后阿尔泰戈壁涵盖了位于蒙古人民共和国境内的准噶尔盆地东端、阿尔泰山南脉以及天山山脉的戈壁支脉。其领土向西北方向延伸，与阿尔泰山脉的走向及与中国国境线的位置相符，它即被夹在其间。后阿尔泰戈壁的东界大致与东经100°30′重合，西界与东经90°30′重合。由于其领土向西北延伸，南界纬度从东部的北纬42°30′上升到西部的北纬45°15′，北界位置也相应变化：从北纬44°30′到北纬46°（见图I）。\n后阿尔泰戈壁作为中亚的内陆区域之一，以极其荒凉著称。分队在那里遇到了巨大的困难，包括区域严重缺水、无人居住、汽车通行条件有限、距离加油站遥远，以及严酷的气候条件（令人疲惫的炎热和空气干燥）。\n分队在后阿尔泰戈壁工作了四个月，在此期间完成了4200公里的概略地质路线调查，覆盖了从东经99°到布勒贡河弯曲处的区域；其中1780公里是骑骆驼和步行完成的，2420公里乘车完成。\n分队完成了八次完整的后阿尔泰戈壁南北向穿越，以及大量限于各个构造-形态区域范围内的部分穿越。踏勘研究所涉及的面积达9万平方公里。采集的岩石标本共计890块；在32个地点收集了志留纪、中-上泥盆纪、杜内期、维宪期、下二叠纪和白垩纪的动植物化石；在42个地点采集了重砂样品。\n由于中亚地区特有的、令人惊叹的良好露头条件，以及拥有比例尺为1:200,000的优良地形底图，尽管路线稀疏，我们仍得以把握后阿尔泰戈壁构造的主要特征，并编制了大致符合1:1,000,000比例尺地图要求的地质图。\n从后阿尔泰戈壁返回后，地质分队沿铁路线完成了从乌兰巴托到苏联边境的路线调查。十月底，分队成员返回祖国。\n室内整理工作在列宁格勒的煤炭地质实验室进行。由于野外材料运送延误，我们直到新年前夕才能开始这项工作。我们的岩石标本连同农业考察队其他分队的标本，一起装在一辆汽车里，而汽车被装载在敞篷平板火车上。在伊尔库茨克地区，这辆汽车发生了火灾，给车内包括我们标本在内的材料造成了重大损失。运抵莫斯科时，样品散乱不堪，包裹烧焦，部分标签丢失。\n由于预留了用于制作薄片的副本，岩石学部分的标本损失未超过30%。古生物标本，特别是那些小块碎片，包装成大捆，在很大程度上损毁了。许多采集点的标本在余下的藏品中已完全找不到，其他点的也只部分保存下来。重砂样品中有三个样品侥幸留存。\n农业考察队预算未涵盖的室内处理工作，仅能部分完成。蒙古委员会从中拨出的款项，远不能满足必要的研究工作量。利用拨付的资金，我们制作了300个岩相薄片（原计划700个），部分支付了化石鉴定费用并打印了手稿。\n原计划进行的专门岩石学和矿物学研究、化石的专著性处理、硅酸盐分析、光谱分析等一系列工作，因缺乏资金而未能实施。\n火灾后幸存的古生物材料由以下人员参与审阅：院士Д. В. 纳利夫金、乌克兰苏维埃社会主义共和国科学院正式院士А. Н. 克里什托福维奇，以及古生物学家Л. Д. 基帕里索娃、Т. А. 亚历山德里-萨洛娃、В. Н. 特里兹纳、Б. В. 纳利夫金、Д. Ф. 马斯连尼科夫、Б. П. 马尔科夫斯基、Е. М. 柳特克维奇、Д. Л. 斯捷潘诺夫和А. М. 奥布特。而化石的主要鉴定工作由Л. П. 莫纳霍娃完成。\n岩相薄片的审阅由野外考察参与者В. А. 阿马什托夫负责；他还为地质概述第二章中关于深成火成岩的描述准备了材料。

Its mission was to conduct a reconnaissance survey of the Trans-Altai Gobi, a region that had not previously undergone geological investigation. The detachment consisted of Dr. V. M. Sinitsyn, a Doctor of Geological and Mineralogical Sciences, and V. A. Amantov, a graduating student of the Leningrad Mining Institute.\r\n\r\nIn Ulaanbaatar, the team was expanded to include the driver A. S. Karabin, the interpreter Dashchik Sambuyev, a third-year student at the Mongolian State University, and a worker named Zhana. On June 10, the detachment departed Ulaanbaatar in an assigned ZIS-5 truck, following the ancient Gobi route through Dalandzadgad and Obotu Khural toward the study area.\r\n\r\nThe Trans-Altai Gobi constitutes the southwestern part of the Mongolian People's Republic and is the region most distant from the capital. There are two routes leading into the Trans-Altai Gobi: one follows the Tsetserleg road through the Khangai Mountains, the Valley of Lakes, and the Mongolian Altai; the other follows the Dalandzadgad road across the Gobi Plateau, crossing only the outlying ranges of the Altai Mountains.\r\n\r\nThe first route leads to the northwestern part of the Trans-Altai Gobi, while the second reaches its southeastern sector. The distance from Ulaanbaatar to the nearest point of the region by either route is approximately the same, about 1,300-1,350 kilometers.\r\n\r\nThe Trans-Altai Gobi encompasses the eastern extremity of the Dzungarian Basin, the southern spurs of the Altai Mountains, and the Gobi extensions of the Tianshan range located within the Mongolian People's Republic. Its territory stretches northwestward, occupying the space between the trend of the Altai Mountains and the frontier with China. The eastern boundary of the Trans-Altai Gobi approximately coincides with 100°30′ E longitude, while the western boundary lies near 90°30′ E longitude. Because the territory extends toward the northwest, the southern boundary rises from 42°30′ N latitude in the east to 45°15′ N latitude in the west, while the northern boundary correspondingly shifts from 44°30′ N to 46° N (see Fig. I).\r\n\r\nAs one of the inland regions of Central Asia, the Trans-Altai Gobi is renowned for its extreme desolation. The detachment encountered tremendous difficulties there, including severe water scarcity, the absence of permanent settlements, limited conditions for motor transport, great distances from fuel stations, and harsh climatic conditions characterized by exhausting heat and extreme dryness.\r\n\r\nThe expedition worked in the Trans-Altai Gobi for four months. During this period, it completed 4,200 kilometers of reconnaissance geological traverses covering the area from 99° E longitude to the bend of the Bulgun River. Of this distance, 1,780 kilometers were covered by camel and on foot, while 2,420 kilometers were traversed by vehicle.\r\n\r\nThe detachment completed eight full north-south crossings of the Trans-Altai Gobi, together with numerous partial traverses confined to individual tectonic-morphological regions. The reconnaissance survey covered an area of 90,000 square kilometers. A total of 890 rock specimens were collected. Fossils of flora and fauna from the Silurian, Middle and Upper Devonian, Tournaisian, Viséan, Lower Permian, and Cretaceous periods were obtained from 32 localities. Heavy-mineral concentrate samples were collected from 42 sites.\r\n\r\nOwing to the exceptionally favorable outcrop conditions characteristic of Central Asia and the availability of excellent topographic base maps at a scale of 1:200,000, we were able, despite the wide spacing of traverses, to identify the principal structural features of the Trans-Altai Gobi and to compile a geological map broadly meeting the requirements of a 1:1,000,000-scale map.\r\n\r\nAfter returning from the Trans-Altai Gobi, the geological detachment conducted a route survey along the railway from Ulaanbaatar to the Soviet border. At the end of October, the members of the expedition returned home.\r\n\r\nLaboratory processing and analysis were carried out at the Coal Geology Laboratory in Leningrad. Owing to delays in the delivery of field materials, we could not begin this work until the eve of the New Year. Our rock specimens, together with those collected by other sections of the agricultural expedition, were packed into a truck that was transported on an open railway flatcar. In the Irkutsk region, the truck caught fire, causing severe damage to the materials inside, including our collections. By the time the shipment arrived in Moscow, the specimens were scattered, packages had been burned, and some labels had been lost.\r\n\r\nBecause duplicate samples had been reserved for thin-section preparation, losses among the petrographic collections did not exceed 30 percent. Paleontological specimens, particularly small fragments packed together in large bundles, suffered far more extensive damage. Specimens from many localities could no longer be found among the surviving collections, while those from other sites were only partially preserved. Of the heavy-mineral samples, only three survived.\r\n\r\nThe laboratory processing work, which had not been covered by the expedition's budget, could only be completed in part. The funds allocated by the Mongolian Committee were far from sufficient to support the necessary volume of research. With the available resources, we prepared 300 petrographic thin sections instead of the 700 originally planned, partially covered the costs of fossil identification, and arranged for the manuscript to be printed.\r\n\r\nA number of studies originally planned, including specialized petrographic and mineralogical investigations, monographic treatment of fossil materials, silicate analyses, spectral analyses, and other related work, could not be carried out because of insufficient funding.\r\n\r\nThe paleontological materials that survived the fire were examined by Academician D. V. Nalivkin; Full Member of the Academy of Sciences of the Ukrainian SSR A. N. Krishtofovich; and paleontologists L. D. Kiparisova, T. A. Aleksandri-Salova, V. N. Trizna, B. V. Nalivkin, D. F. Maslennikov, B. P. Markovsky, E. M. Lyutkevich, D. L. Stepanov, and A. M. Obut. The principal identification of the fossil collections was carried out by L. P. Monakhova.\r\n\r\nThe petrographic thin sections were examined by V. A. Amantov, a participant in the field expedition. He also prepared the materials used in Chapter II of the geological overview concerning plutonic igneous rocks.", "ds_source": "Author (Editorial Board): Expand.М.
