Abstract

To what extent can fine-grained statistical analysis provide evidence regarding syntactic patterns in corpus languages like Sanskrit, particularly in cases where the interaction of multiple syntactic phenomena obscures the evidence? We investigate the value of a correlation matrix for bivariate data analysis in relation to varying syntactic patterns in a relatively poorly attested yet productive construction in Classical Sanskrit: the passive of the causative (‘passive causative’). The interaction of causative and passive is complex in Sanskrit, but we show that even in the case of low frequency data, syntactic conclusions can be drawn from such interactions when detailed statistical analysis is employed. In particular, our analysis speaks to the status of the ergative in Sanskrit.

Abstract

The Caledonian and Ellesmerian orogenies were followed by extension and development of intracontinental rift basins since the late Paleozoic, as represented by the Sverdrup Basin along the Canadian Arctic Islands. The initial rifting was accompanied by pulses of volcanic activity during the Carboniferous and Permian. A new occurrence of mafic volcanic rocks, the 'Taconite volcanics' (informal name), was discovered on northern Ellesmere Island between the head of Ayles Fiord and M'Clintock Inlet. The mainly alkali-picritic lavas are exposed within the central part of the Pearya Terrane as an outcrop in faulted contact with upper Carboniferous red beds of the Canyon Fiord Formation. The contact to the Ordovician island-arc volcanic rocks of the Pearya Terrane is unclear. The outcrop is characterized by a small circular magnetic anomaly. Ar-Ar whole-rock geochronology on the volcanic rocks yielded an age of 290 [+ or -] 19 Ma suggesting emplacement of the lavas during the early Permian. Whole rock geochemical analyses for eight samples revealed a geochemical affinity to ocean island basalt (OIB) and indicate variable mixing of low-degree melts in the fields of garnet and spinel peridotite (~80-90 km depth). The involvement of a metasomatized subcontinental lithospheric mantle is indicated by high Pb, Nb, and Ta concentrations. Geochemical differences (as enrichments in Ti, Nb, Zr, and the light rare earth elements (REE)) to the known Carboniferous and Permian spilitic altered basalt occurrences of northwestern Ellesmere and northern Axel Heiberg islands are probably based on differences in the mantle source. The Sr isotope ratios of the Taconite volcanics are primitive ([([.sup.87]Sr/[.sup.86]Sr).sub.t]: 0.7037-0.7042) and its Nd isotope ratios are moderately depleted ([epsilon][Nd.sub.(t)]: +2.20 to +2.85) in contrast to the enriched s[Nd.sub.(t)] values of the Permian Esayoo formation. Key words: Taconite volcanics, rifting, volcanism, Ellesmere Island, Canadian High Arctic, Sverdrup Basin, 1. Introduction The target area of the expedition CASE 11 (Circum-Arctic Structural Events), organized and led by the German Federal Institute for Geosciences and Natural Resources (BGR), in the summer [...]

3. Comparing geophysical inversion and petrophysical measurements for northern Victoria Land, Antarctica.

Abstract

Bedrock geology from Antarctica remains largely unknown since it is hidden beneath thick ice sheets. Geophysical methods such as gravity and magnetic inverse modelling provide a framework to infer crustal rock properties indirectly in Antarctica. However, due to limited availability of rock samples, validation against direct geological information is challenging. We present a new rock property catalogue containing density and susceptibility measurements on 320 rock samples from northern Victoria Land. This catalogue is used to assess the reliability of local and regional scale inverse results, including a new local high resolution magnetic inversion in the Mesa Range region and a previously published regional scale joint inversion of gravity and magnetic data in northern Victoria Land and the Wilkes Subglacial Basin. We compare our density and susceptibility measurements to global and local measurements from the literature to access the correlation to rock types and geological units. Furthermore, the measured values are compared against inverted values. The close correspondence between inverted and measured rock properties allows us to predict locations of rock types where currently such information is missing. The utility of measured susceptibility and density relationships for interpreting inversion output provides a strong incentive to incorporate local rock samples into geophysical studies of subglacial geology across Antarctica.
