Cordillera, Spain: Sedimentology,. Photomicrographs of the main porosity-modifying cements (continued). Thus, higher matrix contents are closely related to greater compaction but also result in the inhibition of pore-lling cements that prevent IGV loss (Figure 14A, B). He is currently the manager of Sandtrak, the provenance and reservoir quality unit of Chemostrat Ltd. Husets placering og udformning, husets er placeret centralt i bebyggelsen i det grønne strøg mellem blokkene. Dissol.) showing that cement dissolution dominates over that of detrital feldspars, although there are no obvious variation patterns between them. Detrital matrix Figure. The spatial kosläpp helsingborg 2018 distribution of detrital matrix is strongly facies related, as proven by the same distribution pattern that other hydraulic-sorting sensitive variables have, such as rip-up clasts, heavy minerals, and micas. Patches of replacive purple-stained calcite (for its Fe content) have been identied randomly distributed (Figure 9C). In a well-constrained sedimentological framework and with relatively homogeneous conditions of detrital composition, this study aims to determine the effect of depositional fabric on early diagenetic processes and their collective effect on petrophysical properties (pore size distribution, open porosity, and permeability). (B) Plot of compaction porosity loss (copl) and IGV indices versus ductile component abundance (matrix rip-up clasts micas phyllitic grains; point-counting data).
In the study area in Alcaraz (Albacete; Figure 1A the Triassic sedimentary succession (AnisianNorian) consists of 160 m (525 ft) thick, siliciclastic, alluvial-lacustrine and uvial stacked facies organized in three subhorizontal depositional sequences (Figure 1B; Fern andez and Dabrio, 1985; Fern andez., 1993. Sunada, 1977, Ground-water hydrology and hydraulics: Fort Collins, Colorado, Water Resources Publications, 304. Secondary pore results from detrital K-feldspar dissolution (black arrows). Note that gypsum is systematically the most abundant porosity-modifying cement, although its occurrence varies across facies. Husets indretning er tilstræbt enkel og består elementært af 2 dele den offentlige og private et område med arbejdspladser/ beboerinformation og et velfærdslokale, adskilt af en kerne bestående af toilet/bad og depot/print.
