The granitic intrusives in southwest Saqqez are located in the northern Sanandaj Sirjan zone. These granites can be divided into mesocratic and leucocratic granites. The external morphology and internal structures of zircon from these granites have been investigated employing the classic Pupin method supplemented by electron microscope analysis. The zircon crystallization is a function of tempe...

High pressure waterjets are now entering use on an increasing scale for primary rock excavation in quarries. In order to assess the parameters required for any such rock cutting operation a series of experiments need to be carried out in which the critical operational parameters are identified. This paper seeks to identify such a standard procedure with an explanation with the reasons for choic...

At the first site, the Weinsberg (Moldanubian) granite and an older quartzmonzonite facies of the South Bohemian pluton in Austria both contain orthopyroxene and clinopyroxene and must have crystallized from magmas at high temperatures. The granite contains orthoclase megacrysts (as much as 10 to 20 cm long), which (1) are chemically zoned with Ba-rich cores (1 to 2 % mol Cs; and locally as muc...

Abstract Low mechanical resistance and high weight restrict use of natural stones in applications where tensile or flexural capacity is required together with a low weight, such as for long spans or thin sections (e.g., cladding, countertops, desktops). The use of composite laminates as external reinforcement both to increase the mechanical resistance and to decrease weight of natural stone is ...

Many puns create humor through the relationship between a pun and its phonologically similar target. For example, in “Don’t take geologists for granite” the word “granite” is a pun with the target “granted”. The recovery of the target in the mind of the listener is essential to the success of the pun. This work introduces a new model for automatic target recovery and provides the first empirica...
