“…Most of these deposits formed in the late Mesozoic related to the Yanshanian (Jurassic to Cretaceous) magmatism, which is generally attributed to the subduction of the Downloaded by [Guangzhou Institute of Geochemistry] at 00:00 09 February 2012 Pacific plate Zaw et al 2007). Furthermore, MesozoicCenozoic basins were well developed in SE China (Shu et al 1998;Shu et al 2004;Deng et al 2004b); they include more than 100 of different sizes, with a total basinal area of >50,000 km 2 in SE China (Shu et al 2007;Shu et al 2009). …”

Abstract. The southeastern coastal region is one of the most developed and populated areas in China. Meanwhile, it has been severely impacted by acid rain over many years. The chemical compositions and carbon isotope compositions of dissolved inorganic carbon (δ 13 C DIC ) in river water in the high-flow season were investigated to estimate the chemical weathering and associated atmospheric CO 2 consumption rates as well as the acid-deposition disturbance. Mass balance calculations indicated that the dissolved loads of major rivers in the Southeast Coastal River Basin (SECRB) were contributed to by atmospheric (14.3 %, 6.6 %-23.4 %), anthropogenic (15.7 %, 0 %-41.1 %), silicate weathering (39.5 %, 17.8 %-74.0 %) and carbonate weathering inputs (30.6 %, 3.9 %-62.0 %). The silicate and carbonate chemical weathering rates for these river watersheds were 14.2-35.8 and 1.8-52.1 t km −2 a −1 , respectively. The associated mean CO 2 consumption rate by silicate weathering for the whole SECRB was 191 × 10 3 mol km −2 a −1 . The chemical and δ 13 C DIC evidence indicated that sulfuric and nitric acid (mainly from acid deposition) were significantly involved in the chemical weathering of rocks. There was an overestimation of CO 2 consumption at 0.19 × 10 12 g C a −1 if sulfuric and nitric acid were ignored, which accounted for about 33.6 % of the total CO 2 consumption by silicate weathering in the SECRB. This study quantitatively highlights the role of acid deposition in chemical weathering, suggesting that the anthropogenic impact should be seriously considered in estimations of chemical weathering and associated CO 2 consumption.

“…According to Peng [16], the compressive early Yanshanian movement in the Middle Jurassic-Early Cretaceous resulted in two major structural components: 1) NNE and NE trending faults, including the Renhua Fault, belonging to the Wuchuan-Sihui thrust fault belt, which has created a gradually westward-rising structure and 2) numerous E-W to NE-SW vertical joints in the red beds formed during the crustal movement. The NNE-trending faults underwent a left-lateral strike slip during the Cenozoic, controlling the strike of mountain ranges and development of intermontane basins [17]. The two major Fig.…”

Abstract:The "Danxia landform" is an erosional landform type originally defined in China. It is characterized by redcolored sandstones and steep cliffs, and developed via long-term erosion. Detailed quantitative geomorphometric studies of the characteristics of Danxia landforms in China have not yet been conducted. Using GIS, we conducted DEM-based geomorphometric analyses of 42 watersheds on Mt. Danxia, China. This area has many typical Danxia landforms. Analysis of stream networks indicates that fault systems are responsible for the NE-trending stream direction. Hypsometric curves and hypsometric integrals (HI) of the watersheds show that HI is significantly affected by lithology; the lithological difference between the eastern and western parts of the study area are reflected in the general form of watersheds. Longitudinal profiles of the watersheds were used to analyze the stream length gradient (SL) index and Hack profiles, which were also found to reflect lithology and fault control.
