A Survey on the condition of Micro Facies , Sedimentary Environment and the Cretaceous Deposits ( With Particular Reference to Central Iran )
Micro continent of central Iran is a part of middle Iran that is bounded with ophiolithic suture zones in Sistan, Naiin, Baft, Doruneh fault and Kashmar – Sabzevar ophiolites and is classifiable into Lut block, Shotori upland, Tabas subduction, Kalmard upland, Posht Badam block, Biaze Bardsir basin and Yazd block by means of long faults which are dextral strike – slip faults and have westwards inclination. In many regions of Iran, except to Zagros, in approximate boundary of early and late Cretaceous, it is observed evidences of tectonic events which are mainly as land generating and can be compared with worldwide Austrian event, in everywhere in Iran except to rare cases (east of Tehran and Yazd). Upper Cretaceous beds in Iran do not have identical facial characteristics and it seems that in contrast to equal sedimentary condition in early Cretaceous, sedimentary basins in upper Cretaceous have been separated from each other and special condition has been dominated in each basin. As a result of that, lithostratigraphic units except to Zagros and Kopet Dagh have not been named and or have local names in upper Cretaceous of Iran. This article is an overview of the condition of Micro-facies, sedimentary environment and the Cretaceous deposits in central Iran. [Mehran Arian, Hamideh Noroozpour.

Albian decapod Crustacea from Southeast Isfahan, Central Iran- Kolah-Qazi area
The first record for Cretaceous (Albian) crustaceans from Southeast Isfahan, Central Iran-Kolah-Qazi area is provided based on presence of the raninid crab Notopocorystes xizangensis Wang, 1981, as well as callianassoid remains and articles of ?Hoploparia sp. Details of the stratigraphic section were material was collected are provied, as well as a brief review on the previous geologic reports of the study area. Abstract
Archaeological Survey of Dangoyama Kofun by 3DGPR
We presented a three-dimensional ground penetrating radar (3DGPR) system for the archeological investigation in a harsh site, where we have to deal with many trees and/or great topographic variations. This system consists of a commercial GPR system with a laser positioning system. With this system, we can move the GPR antenna freely, on which a positioning detector can record accurate position for each GPR data trace. We applied our 3DGPR system at Dangoyama Kofun, a burial mound, in Fukushima prefecture, Japan. A lot of trees and bushes covered the survey area and cannot be cut. We acquired six datasets in two days in this area. We successfully imaged the boundary between the original surface of the burial mound and the covering soil clearly at about 0.3 m depth around the mound. Furthermore, we found some strong reflections appeared at 0.8 m depth in the top area of the mound, which can be from the artificial parts of the burial mound. The results would greatly aid the following archaeological excavation. In addition, we compared the non-interpolated depth slice with interpolated depth slice at same position and demonstrated that the interpolation process on threedimensional GPR data may introduce some artifacts which might mislead our interpretation.
