Modelling Seismically Induced Mesothermal Goldfields along the Deep-Rooted Cadillac-Larder Lake Fault, Abitibi, Canada [PDF]

open access: goldGeofluids, 2018
Gold deposits are not uniformly distributed along major faults due to complex (and long-debated) interactions between seismicity, hydrothermalism, and structural heterogeneities.

Mobilisation and Bioavailability of Arsenic Around Mesothermal Gold Deposits in a Semiarid Environment, Otago, New Zealand

open access: goldThe Scientific World Journal, 2002
Arsenopyrite (FeAsS) is the principal arsenic (As) mineral in mineralised mesothermal veins (typically 5,000 mg/kg As) in southeastern New Zealand. Groundwater in contact with arsenopyrite-bearing rocks has elevated As concentrations (up to 0.1 mg/l ...

New isotopic evidence for micro and mesothermal valleys camelids from Northwest Argentina

open access: diamondFrontiers in Environmental Archaeology
IntroductionDomestic and wild camelids were the most significant meat resource for pre-Hispanic agropastoral societies in the Argentine Northwest's micro valleys (between 2,500 and 3,400 masl) and mesothermal valleys (2,500 and 1,500 masl), with varying ...

Thermal modelling of orogenic mesothermal deposits : application to Ghana

open access: green, 2005
Cette thèse vise à comprendre les processus thermiques et les régimes d'écoulement de fluides menant à la genèse de gisements d'or mésothermaux. Deux approches de modélisation numérique sont utilisées, une régionale, caractérisant le régime thermique conductif pré-minéralisation et l'autre locale ajoutant la convection hydrothermale syn-minéralisation.

PIC computation of electron current collection to a moving bare tether in the mesothermal condition [PDF]

open access: yes, 2001
In tethered satellite technology, it is important to estimate how many electrons a spacecraft can collect from its ambient plasma by a bare electrodynamic tether.

Spring and autumn phenology in sub-mesothermal beech stands from the southwestern extremity of the Carpathians

open access: goldNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2020
The research carried out was aimed to assessing the phenological behavior of beech (Fagus sylvatica L.) in the southwestern area of the Carpathians, in submesothermal forest sites, differentiated from the majority mesothermal ones of this species. The data obtained may be used for predicting the phenological changes of the species, especially in the ...

Petrology of hydrothermal metasomatism of intra-ore dolerite dikes of mesothermal gold deposits

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
There is a necessity of working up the geology-genetic theory of hydrothermal gold deposit formation instead of the four hypotheses excepting one another: granitogene, basaltogene, metamorphogene, polygene.
