Daletingchagan Pb-Zn-Ag polymetallic ore, located 70 km away to the Baogeda Mountain in Dong Ujimqin, Inner Mongolia, is a Pb-Zn-Ag polymetallic orefield, found based on that Geological prospecting institute of Liaoning province carry out the synthesis method for prospecting project of Baogeda forest field. This mineral deposit could be divided into two ore block, genetic types of west ore block is contact metasomatic type, east ore block is shallow epithermal deposit related to volcanic agencies and the subvolcanic, this paper is mainly on comprehensive study of east ore block mineralization, aiming at providing a beneficial reference of further exploration for concession.

Ambers in China have been described from the various localities of both Cretaceous (e.g., Xixia amber from Henan Province and Jalainur [Zhalainuoer] amber from northeastern Inner Mongolia) and Palaeogene (e.g., Eocene Fushun amber of Liaoning Province and Miocene Zhangpu amber of Fujian Province) ages to date (e.g., Hong, 1981, 2002; Shi et al., 2014; Wang et al., 2014; Azar et al., 2019; Wang et al., 2021). Here we report a new amber locality from the Late Oligocene of Nanning Basin, Guangxi, southern China. The first amber piece was collected by one of the authors (GCZ) on 5 June 2008. In a recent field work in early 2021, we further discovered more than 50 smaller amber pieces, which are reported here.

In the case of attached-rim vessels in Northeast China, the scale of the pottery vessel type was reduced to meet a demand for minimal living of the people at that time due to a way for groups living in low hills of Aohan Qi located in the EastSouth inner Mongolia, and it has emerged from the process of improving the existing double-rimmed deep bowl pottery while focusing on its practicality. Attached-rim vessels that have emerged from Shuiquan Type for the first time spread to regions adjacent to the EastSouth inner Mongolia and the Liaoxi region, attached-rim vessels in the Lioaxi region spread again to the Zhengjiawazi Type located in the midstream of Liao River, and other surrounding areas spread the relevant vessels through the exchange relationship with Zhengjiawazi Type. The attached-rim vessels in Northeast China were distributed only in the Shuiquan Type at the first period(the fifth century B.C.), but in the Zhengjiawazi Type centered in Shenyang at the second period(the fourth century B.C.) as it spread to the triangular area connecting Aohanqi, Kalaqinzuoyi and Ningcheng as well as the Liao River region. At the third stage(the third century B.C.), it became widely distributed mainly in the middle and upper stream regions of Taizi River at Liaoxi and Benxi centered in Chaoyang of Liaoning province and Jilin province, in the middle and upper stream regions from Gou river to Dongliao river, and in the lower and middle stream region of Huifa river). However, at the fourth stage(the first and second centuries B.C.), it was only partially distributed at some sites in the Eastern part of Liaodong and in the South Central of Jilin province, but it finally disappeared.

Moderate Drought

<p>In 2018, severe meteorological drought occurred in the southwest of Northeast China, the  east-central of Inner Mongolia and the east of North China. Drought shows obvious regional and stage nature .In early March, mild to moderate drought appeared in North China, followed by severe drought in parts of northern and eastern of Hebe province. After the middle of April, the drought was alleviated obviously, and the drought in the southwest of Northeast China began to show signs. In  early May, there was mild to moderate drought in the central and eastern part of Inner Mongolia, and the drought in Northeast China developed. From June to early August, severe drought and above occurred in parts of Liaoning province , Inner Mongolia and North China. In mid-August, in addition to Liaoning province and North China, there were scattered light to moderate drought, drought relief in the northern China. In early September, the drought in North China increased and the range spread northward, and there were droughts of different degrees in the whole North China.In winter, there is only mild drought in North China.</p><p>The drought in this region has affected the agricultural production in different degrees. Spring sowing is blocked in the east of Inner Mongolia and the west of Northeast China, and high temperature in summer leads to the development of drought, corn and rice and other crops are adversely affected.</p><p>From spring to autumn, the precipitation in most parts of the drought disaster  area is less than 10-40%, and the temperature is higher than 1-2 ℃. The lack of precipitation and abnormal high temperature accelerated the loss of surface water, which resulted in the occurrence of drought in this area.</p><p>In spring of 2018, the middle and high latitudes are generally controlled by flat air flow, which is not conducive to the establishment of trough ridge, making the northern dry area lack of favorable precipitation conditions; in summer and autumn, the existence of Baikal Lake high-pressure ridge, resulting in circulation patterns that are not conducive to the precipitation conditions in the northern dry area. Among them, the obvious flat air flow in spring and the obvious high pressure ridge in summer are the main reasons for the outstanding drought in spring and summer in the northern arid area.</p>

The results of a comprehensive study of the material composition and microstructure of 20 skull samples taken after blowing out blast furnace № 6 of EVRAZ NTMK JSC are presented. More than 30 minerals and metal phases of different chemical classes were diagnosed in the samples of the skull. Unlike the skull of blast furnaces of other metallurgical plants (NLMK, ZSMK), the skull of NTMK blast furnaces has an abnormally high content of titanium, zinc, vanadium compounds, as well as heavy non-ferrous metals and sulfur. On the basis of a detailed petrographic analysis, 5 structural and genetic types (varieties in composition and origin) of the garnice were identified. The varieties of the garnish contain a large amount of grenal, which is dominated by refractory compounds of titanium and vanadium carbonitrides of the general formula (Ti, V) (C, N).

Comprehensive Study

Volcanic rocks of Yixian Formation were widely distributed in western Liaoning. The Yixian volcanic cycle of early Cretaceous in the Chaoyang basin can be divided into two subcycles. The first subcycle is composed of basalt, basalt andesite and andesite. The second subcycle is composed of trachyandensite and trachyte. The volcanic rocks are characterized by high SiO2, Al2O3, K2O and Na2O, and comparatively low TiO2 components. The volcanic rocks are obviously enriched in incompatible elements, and depleted in compatible elements. The ∑REE of volcanic rocks is high and rich in LREE. The spider patterns are the right-incline, there is a slight low Eu negative abnormality and low Ce negative abnormality. The characteristics show that volcanic rocks of Yixian Formation belong to the high-K calc-alkaline magmatic serious. Comprehensive study shows that the volcanic rocks of Yixian Formation were generated in response to lithosphere extension in the continent intraplate orogenic belt.

Geological Conditions

The iron belt of northern Hebei and Shanxi provinces to western Liaoning province locates in great geological conditions and hosts various types iron mines, so the prospecting potential is huge. The found iron ore with industrial value have sedimentary metamorphic mines with large scale, and followed by magmatic, sedimentary, and contact-metasomatic ore deposits, etc. The iron mineralization of different types is great affiliated with the geotectonic environment of different geological periods, sedimentation, magmatic conditions, that behaviors different mineralization types corresponding to different geological periods in time, behaviors different iron mining area corresponding to different structural location in the space, consists of the iron metallogenic series coupled to the different time and the different genetic types in North China. Based on the analysis to the distribution regularity, ore-controlling factors and metallogenic series of iron mine, we deeped the regional ore-controlling geological condition and metallogenic regularity of iron ore, provided important reference information for regional exploration.
