Travertines formed of crystalline crust have been widely reported, but there has not focus on their geochemical characteristics. We therefore carefully conducted a series investigations and U-Th dating travertine mound mainly composed from Sobcha (southwest China) to determine features geological implications. The travertines dominantly consist granular crystals fan show δ13C 3.4‰ 4.9‰ V-PDB, δ...

Introduction Emerging research and development activities aim to define integrated environments for image analysis and synthesis. From early '90, I.S.O. working groups oriented to formulate standard proposals are involved in the discussion of functional specifications for an unified area of Computer Graphics and Image Processing [ISO]. In 1994, a CNR Project named " Knowledge through Images: an...

Uniaxial compressive strength (UCS) is considered to be one of the important parameters in rock engineering projects. In order to determine UCS, direct and indirect techniques are employed. In the direct approach, UCS is determined from the laboratory UCS test. In indirect techniques determine UCS based on the nondestructive test findings which can be easily and quickly performed and require re...

Fish Lake Valley, in Esmeralda County, Nevada, sits at the southern end of the Mina Deflection where the very active Death Valley-Furnace Creek-Fish Lake Valley fault system makes a right step to transfer slip northward into the Walker Lane. Northern Fish Lake Valley has been pulling part since ca. 6 Ma, primarily along the Emigrant Peak normal fault zone (Stockli et al., 2003). Elevated tecton...

Seismic techniques, which are known as nondestructive geophysical methods, are commonly used by engineers working in various fields such as mining, civil, and geotechnical engineering. They are frequently employed to investigate certain properties of rocks. Ultrasonic measurements can be applied in various application areas such as rockbolt reinforcement1, blasting efficiencies in the rock mass...

The northern Adriatic continental shelf hosts several coralligenous reefs rising from the sedimentary bottom and characterized by three main benthic assemblages, respectively, dominated algal turfs, encrusting calcareous rhodophyte (ECRs) or erect sponges. Bioconstruction bioerosion processes have been investigated using recruitment travertine limestone tiles deployed in a random site for each ...
