JOURNAL FREE ACCESSThe tin in Indonesia is mainly exploited from placers containing cassiterite. Chemical analysis by the author made clear that mother rocks which liberate the placers belong to the tin granites of the Collision type, which has more popularity in Europe and the United States than the Cardilleran type of Japan.
One hundred and nine sampling sites which are located within placers to check the grade distribution indicated that economically rich cassiterite concentrations are limited to an area within 14 to 15 km from the fringes of the granitic mother rocks under the existing topographic and climatologic environment of the Tin Islands of Indonesia.View full abstractDownload PDF (1290K)

Published: 1973
Released on J-STAGE: June 02, 2018
JOURNAL FREE ACCESSBased on hydrographical conditions for rice cultivation, the lowland rice area in the deltaic region of the Chao Phraya river basin in Thailand was subdivided into five zones. The zones were comprised of (1) Main Area of the Old Delta, (2) Chains of Depressions, (3) Retarding Basin of the Delta, (4) Poldered Flat Delta, and (5) Knotty River Area of the Coastal Zone (Fig. 8). Hydrographical conditions were described for each zone. Hydrographical elements taken for the subdivision of the region were; method of rice cultivation, eg. transplanted or broadcast, as an indicator of general water condition in the fields (Fig. 1), date of transplanting as an indicator of the water conditions at the early stage of rice growing (Fig. 2), period of inundation (Fig. 3), depth of the maximum inundation (Fig. 4), date of the maximum inundation (Fig. 5), rate of increase of the water table (Fig. 6), and drainability (Fig. 7).View full abstractDownload PDF (906K) -
