?COMPOSITION, ORIGIN AND ECONOMIC POTENTIAL OF KAKUL, LAGARBAN AND TARNAWAI PHOSPHORITE DEPOSITS OF HAZARA, PAKISTAN*

Abstract

The phosphate rock occurrences at Hazara inPakistan are
apart of Cambrian-Jurassic sequence which hosts rock phos-
phate associated with dolomite and chert.
The geology of the phosphate bearing district of Hazara
which is situated in Northern Pakistan has drawn attention of
leading geologists of the subcontinent for over a century.
Important contributions to the geology of Hazara were made
by Middlemiss [I] and Wadia [2]. After the independence of
Pakistan, extensive studies on geology of the area were made
by Marks and Ali [3] and Calkins and Matin [4]. The Abbot-
tabad district of Hazara assumed further importance when
phosphate was discovered by Latif [5,6]. A number of studies
on Hazara phosphorite deposits were made by British Mining
Consultants and Sarhad Development Authority [7-13].
