Quartz Vein Geochemistry Records Deformation Processes in Convergent Zones

open access: yesGeochemistry, Geophysics, Geosystems, 2021
In several examples of subduction zones, we compared pairs of quartz veins formed either at the lower temperatures of the seismogenic zone (260°C or below), or at the higher temperatures of its downdip limit (∼330°C). All the veins analyzed here are mode

Analysis of Natural Hydraulic Fracture Risk of Mudstone Cap Rocks in XD Block of Central Depression in Yinggehai Basin, South China Sea

open access: yesEnergies, 2021
The Yinggehai Basin is an important Cenozoic gas bearing basin in the South China Sea. With the gradual improvement of gas exploration and over-development in shallow layers, deep overpressured layers have become the main target for natural gas ...

The remarkable effect of organic salts on 1,3,5-trioxane synthesis

open access: yesPetroleum Science, 2016
The effects of organic salts on 1,3,5-trioxane synthesis were investigated through batch reaction and continuous production experiments. The organic salts used include sodium methanesulfonate (CH3NaO3S), sodium benzenesulfonate (C6H5NaO3S), sodium 4 ...

Emission of Rn and CO2 From Soil at Fault Zones Caused by Seismic Waves

open access: yesEarth and Space Science, 2023
In the search for precursors to earthquakes, correlation has been found between geochemical characteristics of soil gases and seismic activity. In this paper we present evidence that seismic waves can trigger emission of soil radon (Rn) and carbon ...

Cerebrospinal fluid pressure [PDF]

open access: yesJournal of Neurology, Neurosurgery & Psychiatry, 1970
The cerebrospinal fluid pressure at the foramen of Monro in man in the recumbent position is less than 100 mm water relative to atmospheric pressure. The oscillations in the pressure wave due to respiration and cardiac pulsation vary with the actual pressure and increase as the overall pressure rises.

CEREBROSPINAL FLUID PRESSURE [PDF]

open access: yesJournal of the American Medical Association, 1917
While there is included herewith the report of a case with data and pathologic material adding strong support to the theory that cerebrospinal fluid is a secretion from the choroid plexus cells, I trust that it may serve a purpose in another direction, namely, that it may encourage more frequent observations of spinal fluid pressure, and especially the

Use of Mohr Diagrams to Predict Fracturing in a Potential Geothermal Reservoir

open access: yesGeosciences, 2021
Inferences have to be made about likely structures and their effects on fluid flow in a geothermal reservoir at the pre-drilling stage. Simple mechanical modelling, using reasonable ranges of values for rock properties, stresses and fluid pressures, is ...
