The REE and trace element analyses were conducted on 17 samples from the ores and wall rocks
of the Bojitian gold deposit (Table 7).
Mineralized zones in the porphyry deposits always has lower resistivity and higher chargeability than wall rocks
because these deposits have high values of sulfidic minerals such as pyrite, chalcopyrite, chalcocite, covelite and bornite [5,3].
The Toijem shear zone is responsible for the exhumation of the hanging wall rocks
before the well-known period of exhumation by extrusion or channel flow of the GHS by the contemporaneous activity of the Main Central Thrust and South Tibetan Detachment System.
One of the primary goals of the drill program is to determine if mineralization is disseminated in wall rocks
around the mineralized structures as suggested by several previous samples.
This high could be interpreted as an area of thick supra-crustal rocks and under-plating by occanic crust that has been associated with the discovery of major gold deposits in Precambrian rocks of the Canadian Shield.Sarissa had previously conducted surface exploration consisting of stripping and blasting work on the historical large scale Gosselin gold bearing quartz stockwork vein systems and wall rocks
found within the central area of the property.
Obtala Resources PLC (Obtala) (OBT.LN), a company that invests in and develops mineral assets in East Africa, has stated that its new Busolwa gold project in Tanzania has produced grab samples that indicate potential for gold mineralisation within the wall rocks
which are left behind by the present artisanal miners.
But the record's title track makes mentions the Falun Gong meditation movement that was banned by China as an "evil cult" and warns "if your Great Wall rocks
, blame yourself", in an apparent message to the country's authoritarian government.
Three fundamental properties influence the rate at which arc magma ascends: i) magma is less dense than the wall rocks
and is, therefore, buoyant, ii) a magma with lower viscosity rises with greater ease than a more viscous magma (therefore, mafic magma generally rises more readily than felsic magma, which is likely to be trapped in magma chambers where it cools to form a pluton), and iii) magma rises more rapidly in an extensional environment than in a compressional setting because widening fractures create space for rising magma to exploit.
Sat on top of the climbing wall rocks
, drank tea and watched the stars
In fact, later-stage base metal-fluorite-rhodochrosite-stage veins that occupy structures that weren't open to the early, greisen stage of mineralization typically are bordered by fresh wall rocks
with virtually no alteration selvages present.
