Mineralisation And Ore Zones

Mineralisation And Ore Zones

Mineralisation is localised along north-dipping structural zones. There are two large ore zones Minifie and Lienetz and several smaller Kapit Coastal Pacific and Borefields in a 3 km2 surface area. The Kapit ore body is hosted by diverse volcano-sedimentary and hydrothermal facies. The coherent facies include basalt diorite and andesite.

Apr 01 1998 Ore fluid salinity might be a key discriminator in the case of the skarns with relatively high ore-fluid salinities being associated with typical gold skarn deposits that are more directly linked to intrusive sources Meinert 1993. The late Palaeozoic Muruntau deposit in Uzbekistan is apparently one example of a post-Archaean higher .

An Introduction To The Geology Of The Tsumeb

This paragenesis is the result of changing ore fluid chemistry temperature and pressure during multiple mineralisation pulses within the deposit as depicted in Figure 3. The age of mineralisation as determined from Pb-Pb radiometric dating is given as between 550 to 580 million years Holmes and Cahen 1957 at which time the overlying Mulden .

Portergeo Database Ore Deposit Description

The ore zone is typically wider than the vein structure up to 5 m due to the presence of mineralised footwall stockwork veins and breccia zones. The vein typically contains coarse-grained disseminated galena sphalerite scheelite and gold Northern Star Resources website 2019. Gold mineralisation at the Raleigh deposit is associated with a .

Ip The ‘Silver Bullet’ To Finding New Ore Zones

shown the technique can accurately identify sulphide mineralisation in multiple zones. This could accelerate the discovery of new ore zones at Kou Sa and rapidly increase the Projects overall resource base. The latest drilling at Kou Sa has identified two new high-grade zones at Prospect 128 and helped confirm a new zone to the west of Prospect .

Mineral Association Gold Mineralization And Deposit Type

The ore minerals are concentrated essentially as brecciastockwork and disseminated type mineralization in central part of the deposit. The stockwork zone has been developed due to ore-associated silica precipitation following the second boiling of the hydrothermal system which was triggered by the Atabek- Slavyanka plagiogranite intrusions.

March New Model For Tanami Gold Mineralisation

New model for Tanami gold mineralisation issue 85 March 2007 Known ore deposits are all located within the more complexly deformed zones and therefore have a direct association with structural anomalies including through-going thrust faults associated pop-up structures and ramp anticlines. The seismic sections show several

Orogenic Gold Mineralization In The Qolqoleh Deposit

Aug 28 2007 This alteration zone is an intermediate zone and has experienced moderate deformation and alteration and thus comprises low-grade sulfide ore and gold mineralization. In zone C the outer parts are characterized by chlorite–sericite alteration zone

Hydrothermal Gold Mineralization And Some Features Of Ore

Onzon-Kanbani area is a western flank of Mogok Metamorphic Belt where gold mineralization is hosted as auriferous quartz-vein with epithermal low-sulphidation characters. Mineralization is closely associated with NE-SW trending fracture or shear zone probably related to the dextral movement of the Sagaing Fault system. Mineralization related hydrothermal alteration is developed as narrow zones .

The northern side of the deposit is bounded by a NE-striking steeply NW-dipping fault. Fault dislocation is also evident within the deposit where disparate ore zones with varying metal ratios grades and vein densities are juxtaposed across fault planes Holliday et al. 2002. Mineralisation at Cadia Hill occurs as chalcopyrite native gold .
