sorkheh-dizaj apatite-iron oxide deposit is located 32 km southeast of zanjan. the area is situated within the tarom subzone of western alborz-azarbaijan structural zone. the oldest units at the sorkheh-dizaj area are eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciate tuff and lapilli tuff which intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton o...

introduction the senj deposit has significant potential for different types of mineralization, particularly porphyry-like cu deposits, associated with subduction-related eocene–oligocene calc-alkaline porphyritic volcano-plutonic rocks. the study of fluid inclusions in hydrothermal ore deposits aims to identify and characterize the pressure, temperature, volume and fluid composition, (ptx) cond...

The Feldspar project aims to develop a domain specific language for Digital Signal Processing algorithm design. From functional descriptions, imperative code (currently C) is generated. The project partners are Ericsson, Chalmers and ELTE, Budapest. The background and motivation for the project have been documented elsewhere [3]. We aim to raise the level of abstraction at which algorithm devel...

Sharply defined veins in :stockworks and siliceous breccia matrix contain metallic mineral assembhges and follow a number of subparallel trends within and marginal to a ] p tassium-feldspar porphyritic dacite. The .porphyritic dacite and metal-bearing veins and breccias exhibit both con-. formable and crosscutting relationships with andesite and dacite country rocks of the Hazelton Group. Vein ...

INTRODUCTION Flexure of a dental composite can be detrimental to the success of a restoration. Flexibility considerations are thus important when comparing dental materials to optimize the success of resin restorations. AIMS AND OBJECTIVES Flexibility of 5.6 x 18.0 x 2.0 mm3 experimental alumina/feldspar and SR ADORO dental composites specimens were compared. It was hypothesized that alumina/...

In the dating of sediments by luminescence methods, to obtain a sample the purest possible as to its mineralogy determines the rest of the analytical procedures. The isolation of the sample minerals is a critical stage due to the impossibility of quantifying the relative contributions to the dose from the different minerals. In this paper we propose a non chemical method to isolate quartz from ...
