The petrology and geochemistry of serpentinized harzburgites within the Feather River Ophiolite in northern California were investigated to constrain the origin of serpentinization. Trace-element systematics indicate that serpentinization was associated almost solely with relatively low temperature hydrothermal addition of seawater and not with the addition of metamorphic fluids associated with...

This paper focuses on constraining the erosion rate in the area of the Allchar Sb-As-Tl-Au deposit (Macedonia). It contains the largest known reserves of lorandite (TlAsS2), which is essential for the LORanditeEXperiment (LOREX), aimed at determining the long-term solar neutrino flux. Because the erosion history of the Allchar area is crucial for the success of LOREX, we applied terrestrial in ...

abstract purpose - the aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. top-down hierarchies are typically characterized by command and control systems of the authority t...

We present PALEO-SEAL, a simple web interface that allows visualizing, querying and downloading Holocene sea-level datapoints formatted following the HOLSEA data template. The is hosted on mySQL database, uses AngularJS. PALEO-SEAL scalable to large datasets can be deployed in few easy steps, require only basic knowledge of SQL HTML. tool released open domain.

Xiong’an New Area, located in the middle of North China Plain, will have been built as a “city future.” Urban planning and construction need to comprehensively consider constraints hydrogeological conditions such aquifer structure parameters. As main this area, paleo-channel is heterogeneous anisotropic, two-dimensional hydraulic conductivity each horizontal direction cannot be obtained from te...

The tectonic setting of South China during the late Paleozoic is essential to understanding geodynamics off eastern margin Pangea supercontinent due its unique paleo-position at confluence Paleo-Tethys and Panthalassic oceans. Limited magmatic matemorphic records in have hampered resolution this setting. Here, we present integrated biostratigraphic, geochronological, isotope geochemical data on...

Abstract Since the Paleozoic, tectonic evolutionary process of eastern Eurasia has been affected by at least three paleo-ocean regimes: Paleo-Asian Ocean, Mongol-Okhotsk and Paleo-Pacific Ocean. However, transition among these ocean regimes is not well understood. Recently, Heilongjiang Ocean was proposed to play an important role during from regime (and later Ocean) regime. Here we report on a...
