A small diorite/granodiorite stock which has a surface outcrop intrudes the limestone, volcanies and the greywarkes. Thermal metamorphism in the intrusive aureole has transformed the limestone to line-silicate skarns. Copper mineralization in pressent in the limestone silicate skarns. The alluvial covered areas are now cultivated for rice and been.<…
Metode spektrometri merupakan metode sederhana dan cepat yang telah dikembangkan untuk penentuan nitrit dan nitrat dalam air, tanah air dan sampel sediaan farmasi. Penentuan nitrit didasarkan pada reaksi yang melibatkan adam sulfanilat dengan metil antranilat sebagai zat penghunung, sedangkan penentuan nitrat didasarkan pada reduksi menjadi nitrit d…

This book. is concerned with remote sensing, 1 that is, with the detection, identification, and analysis of objects or features through the use of imaging devices (sensors) located at positions remote from the subjects of investigation. Remote sensing may be regarded as reconnaissance from a distance, and that distance may range fr…
A direct means of indicating the presence of concealed mineralization would be the ultimate in exploration. In many ways the.induced-polarization (IP) technique comes close to achieving this goal. it has been remarkably successful in locating concealed bodies containing even small percentages of metallic-luster minerals.
