Soil temperature is an important indicator of frozen ground status, driven at least partly by air temperature variability. In this study we apply singular spectrum analysis (SSA) to detect trends and oscillations in annual ...

A large number of seismic records are discovered for the first time in the historical materials about Wudalianchi volcanic group eruption in 1720–1721, which provides us with abundant volcanic earthquake information. Based ...

Jadeitite is a well known but rare rock type that is found only in a few places in the world. Jadeites are always found in the subduction and subsequent continental collision zone, associated frequently with blueschist ...

Work of recent years has convincingly shown that virtually all rift structures, whether continental or oceanic, expand in two directions simultaneously. Thus, the rift undergoes not only transverse extension (spreading), ...

An empirical relationship between compressional wave velocity (Vp) and radiogenic heat generation (A) is frequently used to estimate heat production distributions in the continental crust. Two data sets from Rybach and ...

In this paper we describe the determination of the temperature field and estimation of surface and plutonic heat flows and of the contribution of radiogenic heating to the total heat flux in a particular region (Kura ...

Crystal growth and coprecipitation experiments demonstrate the manner in which surface structure and, in turn, crystal structure influence growth mechanism and trace element incorporation in calcite. Dominant {1014} faces ...

One of the main parameters describing the genetic features of ore deposition in the ocean and its intensity and history is the rate of growth of ferromanganese nodules (FMN). Despite much experimental work in recent decades, ...

Ontogenetic change in δ18O values of the investigated Nautilus pompilius Linne shell in the Philippines (Tagnan, Panglao Islands, Bohol Island area) confirms data, in which Nautilus in the wild shows a marked increase in ...

It is not illogical that acoustic noise in the interior of the earth should be correlated with the moon- and sun-induced earth tides; but while some published data support this view, other investigators cast doubt on the ...
