Based on field survey, chemical and mineral analyses, archaeological data, radiocarbones dates, and pollen diagram, a hypothesis is presented that the rock planes of terraces and their overlying gravels and fine flood sediments were developed
This paper summarizes the dune sands layer of MGS1 stage in Milanggouwan section first, then compares it with the related chemical elements and detrital minerals of modern dune sands, and identifies the time of each layer of dune sands by the age
Exploitation of mineral resource and its influence on regional development and urban evolution in Xinjiang, China
The paper summarizes the mineral resource exploitation development of Xinjiang especially over the last 50 years, and investigates energy industries and their driving forces, directions, and economic impact on the oasis urban system evolution
growth is promoted by the contributions of the increasing mineral resource industry which promotes economic development. The statistical results provide strong evidence to support the argument that mineral resource exploitation has promoted the growth
This study presents O and S isotope data for soluble sulfate minerals in Core DV 93-1. In combination with the sedimentary features and available isotope compositions of carbonate from this core, these isotopic data for sulfate are interpreted
Impact of land-use types on soil nitrogen net mineralization in the sandstorm and water source area of Beijing, China
), potential net N-mineralization, net nitrification, and urea transformations rates. This was done to provide basic data in quantitative understanding of environment and agricultural implications of land-use shift from forest or grasslands to croplands
minerals, grain size, and sedimentary structures. On the basis of the percentage area and thickness of fluvial sand bodies of the total area and thickness of sediments of the same period, there were 3 palaeochannel development stages, or periods of fluvial
(PCA) showed the main peaks at around 430 nm, 500 nm, 530 nm and 650 nm to be from iron oxides in visible region, and around 1414 nm, 1914 nm and 2210 nm to be from water, hydroxyl and clay minerals. In addition, hierarchical principal component
A geologic and mineral resource assessment of Indonesia
This paper presents an assessment of all undiscovered mineral resources in Indonesia by province. In addition to hydrocarbon, study results indicate that Indonesia may be well-endowed in nonfuel mineral resources, particularly in Timor, Nusa
