A New approximate method for directly interpreting gravity anomaly profiles g…

The problem of solving for the shape of a geologic body which exhibits a measured gravity anomaly has no direct solution in the general case.To obtain a satisfactory solution to such a problem with any degree of rigor,one must resort to a trial-and-error (iterative) solution.This problem is discussed for two-dimensional geometry in some detail by Bott(1960)and by Fournier and Krupicka (1973).A…

A Mineral Appraisal of Sumatra

All the information readily available on the geology and mineralisation of sumatera is recast by this report into a single,original and comprehensive thesis. In extending the concept of Plate tectonics to include platform response,this thesis discloses the record of movements that have great relevance to mainland south-east Asia and to the evolution of landmasses in general.

A Menu Driven System For Interpreting and Modelling Geochemical Data Using Th…

A macro is describe by MICIL (1986) as "a named set DATAMINE comands which are executed one by in the logical order in which they occur. The purpose of a macro is to allow frequently used command segquences to be stored and executed as often as required,without the need to retype them each time.Macros also allow complex processing.

A Geostatistical Study on The Variations of The Iron Sand Distribution in The…

The Cikaso iron sand deposit is located in the southern coast of west java. Systematic exploration drilling has been carried out by directorate of mineral resources (Subandoro et. al.,1981). Samples of iron sand are taken by drill holes at a grid of 20 m x 200 m,from which data of thickness and grade are obtained.

A generalized classification of some tungsten deposits and their relation to …

In recent years two new classifications of Cale Alkalie granitoids have evolved in the eastern hemisphere and are currently influencing exploration concepts, particularly in SE Asia. This note arises from considerations of their possible appliction to the further exploration of the pre-Quaternary part of Sumatra for which a Regional Geolog~cal and Geochemical reconnaissance has just been com…
