Soil mineralogy and other properties in forensic investigations

Handwriting in Forensic Investigations

The process of automatic handwriting investigation in forensic science is described. The general scheme of a computer-based handwriting analysis system is used to point out at the basic problems of image enhancement and segmentation, feature extraction and decision-making. Factors that may compromise the accuracy of expert’s conclusion are underlined and directions for future investigations are...

Quasicrystals and Other Aperiodic Structures in Mineralogy

In this article, we first present and discuss eighteenth-century descriptions of minerals that contributed decisively to the development of crystallography. Remarkably, these old crystallographic descriptions included morphologies with symmetries incompatible with an internal periodic order of atoms, which, however, have been recognised to be characteristics of quasicrystals. Moreover, we also ...

Mineralogy and fluid inclusion investigations in the Zarshuran gold deposit, north of Takab, NW Iran

The Zarshuran Carlin-type gold deposit is located about 30 km north of Takab, West-Azarbaidjan Province, NW Iran. Interaction between the ore-forming fluids and the host carbonates and shales resulted in development of the decarbonatization, argillic, alunite, silicic, and sulfide alteration zones in the study area. Based on mesoscopic and microscopic studies on drill core samples, gold mineral...

Archaeology and forensic death investigations.

Historically, the role of the archaeology in forensic death investigation has focused on excavation techniques and documentation of context. Additional skills of the archaeologist relate to familiarity with stratigraphy and soils, collection and conservation of artifacts, and special areas of interest, such as taphonomy. The following discussion surveys the processes by which the methods and pe...
