The freshwater Buir Lake in Khalkh Gol soum, Dornod aimag, is located (47° 51′ 47″ N, 117° 29″ E) on the border of Mongolia and Inner Mongolia, China. northwest northeast part lake swampy, flat rest part. This research paper reveals lithology some major elements content (SiO2, Al2O3, TiO2, Fe2O3, MgO, K2O, Na2O, MnO P2O5) core sediments their distribution along depth Chemical Index Alteration (...

Introduction: Nakhlites are olivine-augite cumulates that formed in flows or shallow intrusions of basaltic magma on Mars [1]. There have been at least 6 independent attempts to determine the composition of the Nakhla parent magma, and at least 14 variants have been published [2-12]. Four distinct methods have been used: 1) mass balance; (2) augite/melt element partitioning; 3) melt inclusions ...

Tại Thừa Thiên Huế, cây nghệ vàng chủ yếu được trồng nhỏ lẻ tại các nông hộ để tự cung cấp. Do diện tích rất ít nên chưa trở thành hàng hóa có giá trị ứng cho thị trường. Ngoài ra, sản xuất trên địa bàn theo tập quán truyền thống, khai thác hết tiềm năng suất và hiệu quả kinh tế. Nghiên cứu này bao gồm tổ hợp lượng đạm kali như sau: 170 kg N + 100 K2O; 200 150 K2O 230 K2O. Đánh chỉ tiêu sinh tr...

Kashmar granitoids of Taknar zone, in north part of Lut block, intruded into volcanic rocks and consist of granites, granodiorites, monzodiorite and gabbrodiorites. They are composed of mainly plagioclase, alkali-feldspar, quartz, amphibole, biotite and pyroxene minerals. Harker diagram variation, including negative correlations CaO, MgO, FeO, TiO2 and V and positive correlations K2O, Rb, Ba, a...

Physico-chemical characteristics and industrial potentials of lepidolites from Ijero-Aramoko pegmatite fields were investigated . Systematic mapping indicates that the lepidolite is associated with steeply inclined pegmatite intruded into the basement rocks of gneisses and schistose assemblages that are in places pulsed with isolated Pan-African granite. The lepidolite has a layered structure, ...

Two glass ceramics in the CaO--P2O5--MgO system with the incorporation of K2O or TiO2 oxides were prepared with the goal of using them as potential bone graft substitutes. The incorporation of TiO2 and K2O led to the preparation of specific crystalline phases in the structure of the glass ceramics, which show different degrees of biodegradation. In fact, the 45CaO--45P2O5--5MgO--5K2O has been p...
