Till 2017, the global graphite resource reserves had exceeded one billion tons, which are mainly distributed in China （0.45 billion tons）, Mozambique （0.14 billion tons）, Madagascar （0.1 billion tons）, Turkey （0.09 billion tons）, Brazil （0.07 billion tons）, and Tanzania （0.07 billion tons）. These six countries include about 92% of the global graphite resource reserves, of which China accounts for about 45% of the world＇s total resource reserves.展开更多

Subordinated types of iron deposits are magmatic, volcanic-hosted and sedimentary ones. This paper briefly introduces the geological characteristics of major super-large iron ore clusters in the world. The proven reserves of iron ores in China are relatively abundant, but they are mainly low-grade ores. Moreover, a considerate part of iron ores are difficult to utilize for their difficult ore dressing, deep burial or other reasons. Iron ore deposits are relatively concentrated in 11 metallogenic provinces（belts）, such as the Anshan-Benxi, eastern Hebei, Xichang-Central Yunnan Province and middle-lower reaches of Yangtze River. The main minerogenetic epoches vary widely from the Archean to Quaternary, and are mainly the Late Archean to Middle Proterozoic, Variscan, and Yanshanian periods. The main 7 genetic types of iron deposits in China are metamorphosed sedimentary type（BIF）, magmatic type, volcanic-hosted type, skarn type, hydrothermal type, sedimentary type and weathered leaching type. The iron-rich ores occur predominantly in the skarn and marine volcanic-hosted iron deposits, locally in the metamorphosed sedimentary type（BIF） as hydrothermal reformation products. The theory of minerogenetic series of mineral deposits and minerogenic models has applied in investigation and prospecting of iron ore deposits. A combination of deep analyses of aeromagnetic anomalies and geomagnetic anomalies, with gravity anomalies are an effective method to seeking large and deep-buried iron deposits. China has a relatively great oresearching potential of iron ores, especially for metamorphosed sedimentary, skarn, and marine volcanic-hosted iron deposits. For the lower guarantee degree of iron and steel industry, China should give a trading and open the foreign mining markets.展开更多

The disequilibrium is the most stressing characteristic in China＇s employment quality. The disequilibrium of this kind of level of the employment quality not only reflects among the areas where the economic development levels are different, but also reflects more differences of the employment quality due to the differences of the worker＇s identity in the labor market. At present, the problems of employment quality in China are mainly reflected in the labor contracts, working time, labor remuneration, job stability, safety in production, job hygiene, social security, and the respects of basic human rights and participating in the democratic management by the laborers, etc. During the economic transition period, the work relation fields in China appear some special colonies, such as the farmer＇s colony, the colony of ownership transformed enterprises, the colony of flexible persons who obtain employment themselves, whose employment quality demonstrates the questions of some peculiar ones and need special concern.展开更多
