The Jiaobei massif constitutes the southern segment of Paleoproterozoic Jiao-Liao-Ji belt in Eastern Block North China Craton, and contains high-pressure (HP) mafic pelitic granulites. HP granulites contain four distinct mineral assemblages: garnet + kyanite +biotite muscovite rutile (M<sub>1</sub>), ternary-feldspar biotite (M<sub>2</sub>), sillimanite perthite anti-perthite (M<sub>3</sub>), plagioclase (M<sub>4</sub>), which M<sub>2</sub> is a typical assemblage. origin these important for...
China is accelerating green and low-carbon transformations of cultivated land to achieve a carbon peak by 2030 actively respond global climate change. Evaluating the use efficiency (CLUE) determining its driving factors help reduce land-use emissions promote land. However, previous emission-based studies CLUE have been insufficient. Therefore, in this study, we explored spatiotemporal characteristics Yellow River Basin (YRB), China, based on emissions. A slacks-based model with undesirable...
The key ecological functional zone plays a significant role in maintaining ecosystem security, water conservation function and environmental protection. However, owing to rapid industrialization urbanization, some zones have undergone great changes land use, which has changed the landscape pattern characteristics resulted risks, affecting regional environment security. In this study, core source area of Middle Route China's South–to–North Water Diversion Project is selected as case study. A...
The resilience of a tourism environmental system (TESR) is an important aspect sustainable growth. Based on the construction evaluation for TESR, this study used 126 prefecture-level cities in Yangtze River Economic Belt (YREB) as case and attempted to explore spatio-temporal evolution features influencing mechanism TESR. primary conclusions are follows: (1) Despite significant improvement TESR YREB, overall level growth rate remain relatively low, with ample potential improvement. (2)...
The Yanshan Movement occurred mainly during the Middle-Late Jurassic, and gave rise to NE trending structures, magmatic events, volcanism mineral resources. transformation evolution of movement Jurassic were investigated from rock assemblage, geochemistry, chronology in adamellites which exposed Xingcheng area, western Liaoning. Two types recognized—biotite with formation age 172–168 Ma garnet-bearing 158–152 Ma. All samples two displayed enriched characteristics high content SiO2...
Ultrahigh‐temperature (UHT) mafic granulites in the southern part of Shiguai area Daqingshan, China, crop out within Shanheyuan Gneiss Khondalite Belt (KB), a Paleoproterozoic tectonic belt Western Block North China Craton (NCC). The UHT occur hypersthene‐bearing dioritic–granitic gneiss as irregular lenses and deformed dike swarms. Four metamorphic generation assemblages (M 1 –M 4 ) are recognized studied samples. M is defined by enclosed orthopyroxene clinopyroxene “red eye” corona garnet,...
摘要: 大兴安岭扎兰屯南部位于中亚造山带东段,兴安地块(XB)与松嫩地块(SB)之间,是探究兴安地块与松嫩地块构造演化过程,乃至中亚造山带东段微地块聚合过程的关键地区. 对该地区出露的花岗质糜棱岩进行地质学、地球化学、锆石U-Pb测年分析,以期查明板块俯冲过程中的岩浆作用特征,并尝试限定兴安地块与松嫩地块碰撞拼合时间.LA-ICP-MS锆石U-Pb测年结果表明,花岗质糜棱岩分为两期:Ⅰ期为早泥盆世(~398.8 Ma),Ⅱ期为晚泥盆世末‒早石炭世(351.6~365.7 Ma). 两期岩石均具有高SiO2(68.20%~77.90%),富碱(K2O+Na2O=6.32%~9.67%),贫镁(MgO=0.22%~0.97%),偏铝质,高钾钙碱性系列的特征. 稀土元素分布模式均为右倾[(La/Yb)N=4.33~10.77],Eu负异常(δEu=0.03~0.13),富集LILE,亏损HFSE,具有Ⅰ型花岗岩的特征. 两期花岗质糜棱岩可能为俯冲背景下岛弧岩浆活动形成的Ⅰ型‒分异Ⅰ型花岗岩....
The tectonic evolutionary history between the Xing'an Block (XB) and Songnen (SB) in eastern Central Asia Orogenic Belt (CAOB) has been hotly debated. In this study, we present a series of new data to provide better constraint on magmatic process during plate subduction its implications for regional evolution XB SB, even CAOB. whole-rock geochemistry zircon U-Pb chronology syenogranite Chaihe area Great Range have carried out. dating results show that was formed Late Carboniferous...
Land use change is the primary force of driving changes in ecosystem services and their interrelationships, negative effects are observed globally, especially poverty-stricken areas. Revealing linkages has profound implications for farmers' livelihoods, ecological protection, regional sustainable development. This study focused on China's contiguous areas, combined remote sensing data statistics from 680 counties during 1980-2020. The quantitative interaction land with were discussed at...
The low–carbon transition of farmland use (LCTFU) is an effective measure to coordinate the development and environment meet China’s “dual carbon” green agricultural transformation goals. We studied spatial–temporal evolution LCTFU further explored driving factors by applying a geographically weighted regression model (GWR) coastal cities Guangdong Province from 2000 2020. results show that (1) temporally, comprehensive, spatial, functional, mode transitions in areas generally declined....
Abstract The Badu Complex is the oldest metamorphic rock in Cathaysia Block which experienced several episodes of metamorphism Especially indosinian reworking southwestern Zhejiang Province, South China. degree reaches granulite facies. However, there still insufficient understanding characteristics Indosinian and many interpretations its tectonic significance. Therefore, we present detailed petrology, mineral chemistry LA‐ICP‐MS zircon U‐Pb age this paper from pelitic granulites Complex,...
The Mashan Complex of the Jiamusi Massif was traditionally considered as oldest stratigraphic sequence in eastern NE China. However, metamorphic degree is different areas, which can be divided into Jixi–Mishan–Hulin granulite facies belt and Luobei–Huanan–Mudanjiang amphibolite belt. Here, we investigated Yilan area present lots new petrological, mineral chemical, geochemical, U–Pb geochronological data, addition to phase equilibria modelling, constrain timing metamorphism, P–T conditions,...
