A transgression of the Tethys Ocean occurred in east central Iran, like in other areas of the Tethys Ocean, around the Yakhtashian/Bolorian (regional chronostratigraphical units corresponding with the Artinskian/Kungurian of the Early Permian) transition. This led to the development of a carbonate platform that is represented in the Shirgesht area on the northern part of the Tabas Block by the Bagh-e-Vang Formation, which constitutes the only known sedimentary unit from the late Early Permian in Iran. Field data and thin-section analysis indicate deposition on a carbonate ramp with barriers separating a lagoonal area with intertidal mud flats from the open-marine environment. The overall transgres-sive development is indicated by the presence of open-marine sediments on top of the barrier and lagoonal sediments.

The sediments of the Cretaceous Gyeokpori Formation in south-western South Korea accumulated in a lake in which mainly siliciclastic rocks were deposited, with some interbedded volcaniclastics. The nearby volcanic activity resulted in unstable lake margins inducing a dominance of gravity-flow deposits. The high sedimentation rate facilitated soft-sediment deformation on the sloping margin. The deposition of numerous gravity-flow deposits resulted in a vertically heterolithic stratification. The slumps are composed of different lithologies, which is expressed in different types of deformation due to the difference in cohesion between sandy and mussy layers within the slumps. Coarser-grained (cohesionless) slumps tend to show more chaotic deformation of their lamination or layering. The difference in slumping behaviour of the cohesive and non-cohesive examples is explained and modelled. A unique soft-sediment deformation structure is recognized. This structure has not been described before, and we call it ‘envelope structure’. It consists of a conglomerate mass that has become entirely embedded in fine-grained sediment because slope failure took place and the fine-grained material slumped down with the conglomerate ‘at its back’. The cohesive laminated mudstone formed locally slump folds that embedded the non-cohesive overlying conglomerate unit, possibly partly due to the bulldozing effect of the latter. This structure presumably can develop when the density contrast with the underlying and overlying deposits is exceptionally high. The envelope structure should be regarded as a special – and rare – type of a slumping-induced deformation structure.

W artykule omówiono okładziny ścian i sufitów zaprojektowane i wykonane w Wielofunkcyjnej Sali Koncertowej w Toruniu. Były to elementy nowatorskie, opracowane przez głównego architekta obiektu, prof. Fernanda M. Menisa. Wykonano je jako konglomerat składający się z betonu oraz z gruzu ceglanego lub potłuczonego tufu, poddany odpowiedniej obróbce powierzchniowej. Opisano również wykonane w laboratoriach uczelnianych badania dotyczące tych okładzin.

The article presents the wall and ceiling hard finishes designed and made for the Concert Hall in Toruń. They were innovative elements developed by the object’s main engineer, professor Fernando M. Menis. They were made as conglomerates consisting of concrete, brick rubble and crashed tuff – a rock of volcanic origin. The conglomerate underwent an appropriate surface processing. Additionally, studies concerning these hard finishes, conducted in university laboratories, were also described.

Dąbrowska, M. and Jurewicz, E. 2013. Character and structural evolution of the Mała Łąka Fault in the Tatra Mts., Carpathians, Poland. Acta Geologica Polonica, 63 (1), 137-151. Warszawa. The Mała Łąka Fault in the Tatra Mts. is a synsedimentary normal fault responsible for the variable thickness of Eocene deposits in the area. Its main activity took place in the interval from the sedimentation of red conglomerates to the appearance of nummulitic limestones. The estimated throw is up to 350 m. Near the northern margin of the Tatra Mts., the trend of the fault changes from N.S to NE.SW. This part of the fault could have been activated during the Neogene uplift of the Tatra Mts. and rejuvenated as a sinistral fault. In the upper reach of the Mała Łąka Stream, the fault trend does not follow the course of the Mała Łąka Valley. Here, the flowing stream waters used extensional fractures within a damage zone associated with the Mała Łąka Fault rather than the lithological boundary at the tectonic contact between the Triassic dolomites and the Eocene conglomerates. The fault has a hingelike character; its hinge was located in the present-day Kościeliska Valley, c. 2.5 km west of the Mała Łąka Valley.

Artykuł opisuje przebieg prac nad rozwojem konglomeratowych baz wiedzy w kierunku opracowania metodyki dla zastosowań inżynierskich. Jednym z pierwszych działań jest podjęcie próby zdefiniowania schematu i instancji bazy. Taki podział jest konieczny, aby zapewnić środki techniczne do ustanowienia ograniczeń związanych z kontrolą przebiegu procesu projektowania bazy oraz jej późniejszego użytkowania.

EN

The paper presents advances of s-modular approach towards developing design methodology for engineers. One of the first proceedings is an attempt to define and differentiate a schema and an instance of a knowledge base. Such distinction is necessary to provide technical means for establishing constraints to control the process of knowledge base design, maintenance and deployment.

W ostatnim okresie obserwuje się w kraju wzrost zainteresowania kamieniem budowlanym jako materiałem do stosowania w budownictwie, szczególnie z przeznaczeniem na elewacje budynków i do inwestycji wewnętrznych. Przedstawiono dane dotyczące wydobycia i importu kamienia naturalnego oraz jego podstawowych zastosowań. Omówiono zagadnienia związane z normalizacją obejmującą wymienione zagadnienia. Podano również dane na temat PN-EN dotyczących konglomeratów kamiennych.

In last period, the rising application of natural stone products in construction is observed in Poland. In paper, the data dealing with extraction and import of natural stones, main direction of application and current European standards are discussed. These standards are discussed in three following groups: terminology, test methods and natural stone products. Additionally, the standards concerning the stone conglomerates are characterized.
