The Karakoram terrane in Northern Pakistan is geologically equivalent to the Qiangtang terrane of central Tibet but unlike Tibet shows extreme topographic relief, high uplift-exhumation and erosion rates and exposes deep crustal metamorphic
and igneous rocks of the lower crust. The Karakoram terrane has been above sea-level since Early to Mid-Cretaceous, the age of the youngest marine sedimentary rocks. Geological and U-Pb geochronological data show that the Karakoram Range was a dynamic active

approach. They discuss the important issues that arise : a variety of choices must be made in choosing the prior, both in what geological insights to include and in how to include them.
Geological features, technological characterization and weathering phenomena of the Miocene Bryozoan and Lithothamnion limestones (central-southern Italy)
-petrographical and engineering geological data about BLL are reported and the relations between the lithofacial and technical features of this stone are investigated. Finally the main weathering phenomena affecting the stone were recognised through a detailed
A new geological map the central-western part of the Karakoram belt (Northern Areas and North West Frontier Province, Pakistan) is presented with its explanatory notes. The map is printed at a 1:100,000 scale, summarizing original field surveys
Morphotectonics of the Concud Fault (Iberian Chain, Spain) : comparing geomorphic and geologic indices of activity of an intraplate extensional fault
The results of geomorphic analysis of the Concud fault-generated mountain front (central Iberian Chain, Spain) are introduced into classifications of fault activity proposed by previous authors, and compared with slip rates calculated from geologic

channels and the width of the mainstem upstream and downstream of the confluences was analysed. It was observed that, over the whole reach, a slight narrowing occurred immediately below tributary junctions. The geological control observed suggests
that complex factors play important roles in determining changes to channel width across large systems and that simple cause-effect relationships do not hold in such complicated geological settings.
The AA. use geological mapping and cluster, principal component, and factor analysis to group soils in the Taleghan Drainage Basin in Iran and subsequently determine their erodibility. Physical and chemical properties that might impact soil
erodibility were used to create a matrix of soil properties and parent material. Application of cluster analysis and factor analysis to the data allowed identification of 3 geological (parent material) clusters. To investigate the mutual effect of land use
and parent material on soil erodibility, a soil erodibility factor was obtained for 3 land use types in each cluster: rangeland, cropland (irrigated), and dry-land farming (nonirrigated). The study suggests that geological and land use maps provide a useful

historical resources and geological data are available, allowing to infer the possible effects of meandering at the bifurcation, changing channel widths, vegetation in the abandoning channel and sedimentation independently from the model. Furthermore the AA
. reconstruct the sedimentary styles associated with the bifurcation from a geological cross-section, in particular channel migration, channel widening and narrowing and channel belt formation up to the residual channel stage.
Here, the AA. couple acoustic surveys with georeferenced videography to describe the primary spatial and geologic features of spawning aggregation sites for four economically important species: gag (Mycteroperca microlepis), scamp (M. phenax), red

Data from 23 U.S. Geological Survey (USGS) streamgages were analyzed to assess the geomorphic effects (short-term change and subsequent recovery) of the record 1951 floods on streams in eastern Kansas. Flood-related, channel-bed elevation change
