In order to understand further the emplacement (i.e., volcanic growth) of 22 Icelandite and 3 Rhyodacite cooling units in one long sequences known as Mauna Kuwale Wai’anae volcano (ca. 3.3 Ma), Oahu Hawaii we have conducted appropriate rock magnetic experiments described below well anisotropy susceptibility (AMS) studies such 25 units. We undertaken investigations continuous partial thermo-magn...

In this study we address the question of whether Tharsis rise that occupies ~25 % surface area Mars was once covered by an ice cap, and sudden ice-cap melting responsible for catastrophic development Late Hesperian (3.5-3.6 Ga) circum-Tharsis giant (>1000s km in length) outflow channels. To achieve goal, conducted geomorphologic mapping across Oudemans crater basin (~125 diameter) at elevations...

Introduction The Coastal terrace is a unique tectonic complication in Iran and covers more than half of the Oman Sea coast from Jask to Quatre. These beaches are constantly rising and this has greatly influenced the morphology of the formation and deformation of Makran coasts marine terrace, which can be seen in the formation of coastal cliffs in these areas. But one of the important quest...

A magnetic gradiometer survey was undertaken over an area of approximately 1.3ha, centred on the upstanding remains of the St Lythans chambered tomb (NPRN 227289). The survey is interpreted as showing multiple, often rather subtle, sets of lineations representing both joints in the underlying bedrock and relatively recent agricultural activity. Historical use of the site is shown by a former fi...

This study considers the use of the joint location techniques for sets of Virginia earthquakes recorded by different station distributions. These input data sets consist of microearthquakes (mb < 3) recorded by local networks (post-1978) and larger, felt events (m~ _-< 4.6) that occurred in the same areas prior to network installation (pre-1978). Very different epicentral geometries (both linea...

Introduction: The CM carbonaceous chondrites have been aqueously altered to various degrees in a parent body environment. The least altered members of the group are highly sought after as they can provide valuable insights into the nature of the nebular materials that were accreted to form their parent asteroid(s). Those materials that were most susceptible to aqueous alteration were glass, mel...

New Zealand’s newest and most active volcano, Mt. Ngauruhoe in the Taupo Volcanic Zone, produced andesite fl ows in 1949 and 1954, and avalanche deposits in 1975. Potassium-argon “dating” of fi ve of these fl ows and deposits yielded K-Ar model “ages” from <0.27 Ma to 3.5±0.2 Ma. “Dates” could not be reproduced, even from splits of the same samples from the same fl ow, the explanation being var...

the first half of safavi period is one of the golden age of iran`s book designing and specific styles and schools has been created in various cities at this time. one of the most important schools throughout the history of book design has played key role in art is shiraz school .the peak manuscripts of handwriting and qurans illuminated in shiraz was in the ninth and tenth centuries ah. the ris...

introduction the investigated area is situated in the south west of the khorasan razavi province along the north west of the lut block. different types of metal ore bodies along with non-metal deposits have already been documented in the lut block (karimpour et al., 2008). most of the study area is covered with granitoid rocks. metamorphic rocks with unknown age are present in the north of the ...
