The aim of the publication was to compare suitability foundation soils on basis table (standard empirical) bearing capacity. Four basic groups were compared, which are fine-grained soils, sandy gravelly and rocky soils. scientific motivation for this comparison is that visualizing difference between unsuitability a particular soil / rock one fundamental problems in engineering geology. Quantify...

INTRODUCTION The 2.0 Ga iron-bearing Gunflint Formation was deposited during a transitionary period in Earth history when a stable oxic atmosphere was being established. The Animikie Group, which comprises both the Rove and Gunflint Formations, extends NE-SW for approximately 175 km from Thunder Bay, Ontario to northern Minnesota [1]. The thickness of the Gunflint ranges from 100 to 180 m, with...

A uranium-lead zircon age for a volcanic ash interstratified with fossil-bearing, shallow marine siliciclastic rocks in the Zimnie Gory section of the White Sea region indicates that a diverse assemblage of body and trace fossils occurred before 555.3 +/- 0.3 million years ago. This age is a minimum for the oldest well-documented triploblastic bilaterian Kimberella. It also makes co-occurring t...

the study area is located in the central iranian tectono-magmatic zone, which is known for its world-class ioa-type iron ore deposits. the advanced space borne thermal emission and reflection radiometer (aster) and landsat enhanced thematic mapper plus (etm+) image-processing techniques, were used in satellite imagery through conventional and also modern processing methods including band ratios...
