STYLES OF IRON ORE MINERALIZATION AT THE SCHWANER MOUNTAINS AREA, SOUTHWEST KALIMANTAN, INDONESIA by , KYAW ZIN LATT, , Dr. Lucas Donny Setijadji

“…The purpose of this research is to study of the style of each iron ore mineralization and their mineralogical and geochemical characteristics of different iron ore mineralizations associated with granitic intrusions as well as the geochemical characteristics of granitic rocks. During this research, four iron ore mineralizations are visited to study their nature, style, petrographic studies and significant geochemical characteristics of each iron ore. …”

Fault triggering mechanisms for hydraulic fracturing-induced seismicity from the Preston New Road, UK case study by Kettlety, T, Verdon, JP

“…However, in very tight reservoir rocks, unless a fracture network exists to act as a hydraulic conduit, the rate of diffusion may be too low to explain the spatio-temporal evolution of some microseismic sequences. …”

Cretaceous-tertiary carbonate platform evolution and the age of the India-Asia collision along the Ladakh Himalaya (northwest India) by Green, O, Searle, M, Corfield, R, Corfield, R

“…A regional unconformity across shelf and suture zones above these rocks marks the beginning of continental red bed deposition (Chulung-la and Nurla formations). …”

Investigation of thallium fluxes from subaerial volcanism - Implications for the present and past mass balance of thallium in the oceans by Baker, R, Rehkämper, M, Hinkley, T, Nielsen, S, Toutain, J

“…When considered together with published Tl-Pb abundance data, the measurements provide globally representative best estimates of Tl/Pb = 0.46 ± 0.25 and ε²⁰⁵Tl = -1.7 ± 2.0 for the emissions of subaerial volcanism to the atmosphere and oceans (ε²⁰⁵Tl is the deviation of the ²⁰⁵Tl/²⁰³Tl isotope ratio from NIST SRM 997 isotope standard in parts per 10,000). Compared to igneous rocks of the crust and mantle, volcanic gases were found to have (i) Tl/Pb ratios that are typically about an order of magnitude higher, and (ii) significantly more variable Tl isotope compositions but a mean ε²⁰⁵Tl value that is indistinguishable from estimates for the Earth's mantle and continental crust. …”

Moisture generation and transport at ice stream margins by Gyorffy, A

“…Solutions are identified under constant stress boundary conditions, achieving a stable steady-state porosity φ of 2% assuming a viscosity constant λ much larger than that used from analogy with mantle rocks. That is, we predict that the viscosity of glacier ice is much more sensitive to changes in porosity than that of the mantle. …”

Measurement of properties of the lunar surface using the Diviner Lunar Radiometer experiment on the NASA Lunar Reconnaissance Orbiter by Thomas, I

“…</p><p>The uses of the mid- and far-infrared have been described herein, utilising calibrated Diviner observations to: [1] map the temperatures of the lunar poles; [2] investigate regions containing higher than average abundances of rocks; and [3] determine the composition of regions of the lunar surface by combining observations with the new spectral library made during this project.…”

Surface slip distributions and geometric complexity of intraplate reverse-faulting earthquakes by Yang, H, Quigley, M, King, T

“…Of the total combined (summative) length of all surface ruptures (∼148 km), 133 km (90%) to 145 km (98%) align with the geophysical structure in the host basement rocks. Surface rupture length (SRL), maximum displacement (MD), and probability of surface rupture at a specified Mw are high compared with equivalent Mw earthquakes globally. …”

Petrogenesis of arc-related peridotite hosted chromitite deposits in Sikhoran-Soghan mantle section, South Iran: evidence for proto-forearc spreading to boninitic stages by Sepidbar, F, Khedr, MZ, Ghorbani, MR, Palin, R, Xiao, Y

“…Trace and REE element patterns of Soghan-Sikhoran rocks are similar to those in SSZ peridotites. The studied ophiolites show relatively moderate to high oxygen fugacities (ƒO2), with log units ranging from −0.4 to +0.4 for harzburgites, +0.2 for lherzolites, from − 0.7 to + 2.5 for pyroxenites, from +0.8 to +2.2 for dunites, and from + 0.6 to + 0.8 for chromitites. …”

Geochemistry of oceanic anoxic events by Jenkyns, H

The nature and origin of gold mineralization at Damang mine, Ghana by White, AJR

“…This decompression led to the formation of the fault-fracture mesh, which was enhanced by the silicification of host rocks during an earlier ‘Pink Haematite’ hydrothermal event that was associated with the intrusion of voluminous dolerite bodies.…”
