This study uses taphonomic, sedimentologic, and stratigraphic evidence from fossiliferous beds in Marblehead Quarry to review two hypotheses: 1) that the fossiliferous beds at Marblehead Quarry represent a series of in situ paleocommunities, and 2) whether fossiliferous concentrations in carbonate environments are primarily caused by periods of low net sedimentation. The fossiliferous beds of M...

A 52-year-old woman with nonspecific left leg pain was examined by Tc-99m methylene diphosphonate (MDP) bone scintigraphy. The patient had been a marble quarry worker for 10 years and had developed chronic congestive heart failure secondary to pneumoconiosis. Her hemoglobin analysis and hematologic findings were interpreted as being consistent with sickle cell beta+ thalassemia and also hypersp...

A common thread throughout our discussions was the importance of good operations management to success in a very competitive market environment. Mining is not unique: Since the 1980s, efforts to improve management (epitomized by benchmark companies such as General Electric and Intel) have been undertaken throughout the business community. Improving mine organization and management practices has...

Quarries represent ‘landscapes archives’ as they supplied the stone required for historical buildings. Among them, Caumont ancient quarry stands out in northern France, with its huge dimensions and role, providing building stones at a regional scale since least Middle Ages. The present study aims to approach quarrying methods used over time by means of an optimized methodological approach. desi...

Davydiv ridge constitutes a distinct geomorphological natural region situated within the marginal zone of Podillia Upland, which forms part northern ledge Podillia. The is also considered eastern segment Lviv Plateau. This comprises 19 quarries, majority are no longer operational. Predominantly, these quarries extract sand, with smaller proportion dedicated to limestone and loam excavation. In ...

Proteopithecus sylviae is an archaic anthropoid from the late Eocene quarry L-41, Fayum Province, Egypt. The dentition of Proteopithecus is very primitive and does not closely resemble that of other, better known, primates from the Fayum (e.g., parapithecids and propliopithecids). The dental morphology, much of which is described herein, shows a platyrrhine-like level of organization, suggestin...
