Examples include those in the (1) well-known Cenozoic Izu-Bonin-Mariana (IBM) forearc and the Tonga Ridge, associated with intense mantle depletion at shallow depths in the proto-arc wedge as subduction initiation proceeded43 (i.e., less than c. 2 GPa or c. 60 km); and (2) ...
The movement of NO3-N through groundwater flow to streams was relatively slow, and NO3-N experienced substantial losses in shallow aquifers (Starr et al., 1996, Sprague and Gronberg, 2012). From the hierarchical partitioning analysis in the study, the most influential water-quality variable was...
In this way, the complex sedimentation on the oceanic crust with abyssal sediments and turbidite deposits mixed with green rocks and other sediments of shallow depth is vision already present as early as 1924. He indi- cates further that if compression replaces traction, it is here that the ...
The danger is that shallow minds will believe that riddles have found a solution, whereas they have just been brushed to the one side and replaced by another puzzle of much broader implications, and even more impenetrable.'' Yet in some of his research work, Wegmann strove to make his ...
(7) the multiple-stage volcanic complex of the Kremnické vrchy mountain range, (8) the rhyolite dome/flow complex and related volcanoclastic rocks of the Jastrabá forma- tion, (9) a late stage calc-alkali basalt/basaltic andesite volcano and scattered shallow intrusions and lava flows, (10...
Since Steinmann’s work in the beginning of the last century (Steinmann1905), many studies in the Alps have dealt with the stratigraphic and sedimentary evolution of the Alpine Tethys, showing a change from shallow- to deep-marine sedimentation as rifting progresses (Bernoulli and Jenkyns2009). ...
The only exception to the postulated cold origin of these lacustrine sediments is the single interval of Lithotype 3d that contains many characean-oogonoids as well as some gastropod and mussel shells. This layer was likely deposited in a shallow lake under warmer conditions as it is found ...
Because of the shallow intrusive level, cooling was fast, and hence, no ductile deformation feature was observed. Dykes were emplaced into the westernmost parts of the pluton and both into the medium- and low-grade metamorphic rocks, crosscutting earlier formed detachment zones. N–S trending ...

(1975), tetraploidy principally can be reversible which is part of polyploid evolution. Tetraploids producing lower- or even higher-ploidy offspring may be detrimental for survival due to minor cytotype exclusion as a function of ploidy shift frequency. Hence, we also documented all cases of ...
