Numerical classification of multivariate petrographic presence absence data by association analysis in the study of the Miocene Ziqlag reef complex of Israel
Stratigraphic and petrographic study of foredeep molasse sediments, which provide a detrital record of the evolution of the southern Himalayas during the tectonic collision of central Asia and India.
In this paper we present new results from sediment-petrographic analyses and discuss the vertical as well as cross-valley compositional variation in till. - (l'A)
A preliminary examination of the glacial geology of Co. Longford is presented. Four lithologically distinct facies of diamicton and three associated glaciofluvial members are examined in terms of their petrographic composition. The units
By means of lithological characteristics and the results palaeontological, sediment-petrographical and radiocarbon analyses, the lithology, the palaeo-environmental conditions, the distribution, stratigraphical position and age of the Pleistocene
This paper reconstructs the State of the Art on the Peloritani Crust (Southern Italy). It illustrates the geometry, the real extension, petrographic and geochemical compositions and the techtono-metamorphic evolution of its terrains, with special
Geoprotection in the Drawskie Lakeland is achieved by means of some 10-20 listed objects conferring protection upon inanimate nature. A recent addition to the list is a petrographic garden in the Połczyn-Zdrój area, which gathers together some 51
has been written. The inventory entry for each erratic includes its dimensions and weight, provenance and attributes as regards age, as well as an identification of petrographic type. Attention is also paid to examples of the impacts of morphogenetic
processes that have modified the surfaces of the rock specimens. Details are given of plans for the establishment of a Geopark here, within which the petrographic garden would represent a valuable geosite. – (BJ)
that the weathering process is characterized by at least 2 major stages, having 2 distinct rock microfabrics. The determination of quantitaive petrographic indices provides a measure of the various stages of weathering.
