Fertilizer minerals in Asia and the Pacific

This publication is volume one of Mineral Concentrations and Hydrocarbon Accumulations in the ESCAP Region Series with this collection of papers from its Workshop on the Occurrence, Exploration, and Development of Fertilizer Minerals of the Asia and Pacific region. The Workshop on Occurrence, Exploration and Development of Fertilizer Minerals was organized jointly by the Mineral Resources Section of the Natural Resources Division of ESCAP, the Regional Mineral Resources Development Centre (RMRDC), and the Department of Mineral Resources (DMR) of the Government of Thailand on 26-30 August 1986. These collected papers are the documents which flowed from that Workshop. They include 15 papers presented by resource persons and 13 papers by experts of developing countries of the region.Report........................................................................................................................................................................................ 1 Part One Papers of Resource Persons 1.
