Our mines produce it in its purest state and without adulteration, and as it is only manufactured so as to be in the best condition for your use, we respectfully ask you to give it a trial. Kluor Spar, when exposed to heat, sends forth fumes of the most powerful fluxing, searching, purifying kind known to science, and these fumes, coming into contact with the silicates and impurities in metals, drives them out. Phosphorus and sulphur, that bllfjbear to all metals, is volatilized at once and passes off, leaving a clean, clear residue which flows without hindrance or obstruction until the last ounce of metal contained in the charge is withdrawn.

The Oconee Group is formally recognized in the Savannah River area and four South Carolina Formations not previously used in Georgia by the Georgia Geologic Survey are recognized in eastern Burke County. The Still Branch Sand is a new formation and the two new members are the Bennock Millpond Sand Member of the Still Branch Sand and the Blue Bluff Member of the Lisbon Formation. The four South Carolina formations recognized in eastern Burke CountY include the Steel Creek Formation and Snapp Formation of the Oconee Group, the Black Mingo Formation (undifferentiated), and the Congaree Formation. The Congaree Formation and Still Branch Sand are considered to be lithostratigraphic components of the Claiborne Group.

  • A Bibliography of American Foraminifera

Lecturer in Micropalaeontology, Harvard University and Director, Cushman Laboratory for Foraminiferal Research SHARON, MASSACHUSETTS, U. S. A. DECEMBER, 1932 Price $1.10, post paid QL # « 368 r CD' A BIBLIOGRAPHY OF AMERICAN FORAMINIFERA By Joseph Augustine Cushman The intensive work now being done on the Foraminifera in America and the increasing amount of new literature appearing in scattered journals is the basis for the present bibliography. Primarily the object is to give to the worker on the Foramin- ifera reference to those papers which deal with American genera and species. Papers by American authors which are of a general nature and have no bearing on the faunas are not included. Also papers of a purely geological nature are usually left out unless they have included authentic names of foraminifera with localities or ranges. Numerous earlier works of an historic in- terest as giving the first records of foraminifera from a particu- lar region are included. These appear in the form in which they appeared in Sherborn's excellent Bibliography so that no con- fusion may result in comparing the titles. In order to be of more use to the specialist, one or more letters in bold type will be found at the end of each title, R=Recent; letters T=Tertiary; C=Cretaceous ; and P=Palaeozoic. These indicate the main scope of the paper. In some cases a single let- ter will be found where the paper covers more than one of these groups, but that one refers to the Afnerican records only.

This series of reports began in the summer of 1959 and has continued each succeeding summer—this being the third published bulletin. The author follows closely the pattern previously set, in that he describes in detail the geologic units that crop out along the route and points to specific locations for obtaining suitable topping material. He also describes the structural and geomorphic features exhibited. The writer has properly acknowledged the personnel of the Mis sissippi State Highway Department for their cooperation, nevertheless, it is fitting that these men be recognized here—Mr.

North of this field the Hosston is difficult to identify because th e entire Lower Cretaceous section grades into an undifferentiated sequence of discontinuous sands and shales. Within th e Interior Salt Basin, where virtu­ ally all of the Hosston/Sligo oil and gas produ ction is found, the Hosston and Sligo Formations consist of approx­ im ately 3500 feet of alternating sands and shales fo und at depths of 10,000 · 17,000 feet The sandstones are pink and white to gray in color and are associated with maroon, gray, or mottled mudstones as well as occasional limestone nodules and traces of lignite .

By EDWARD \VILBER BER · INTRODUCTION. The unequaled series of older Tertiary deposits of the I ulf Coastal Plain comprise several thousand feet of sands, clays, marls, lignites, and impur~ limestones. These deposits have always been considered as forming an uninterrupted and ponformable series, extending from the lower Eocene (Midway) to the top of the Oligocene ( ~icksburg and Apalachicola). It is the purpose of the present paper to show that the strand line migrated back and forth over this area several times during the· period represented by these deposits, and that the sedi­ mentation of Eocene time was interrupted during several intervals, of considerable duration in terms of organic evolution. I have attempted to indicat~ the geologic history of the embay­ ment Eocene in a general way in the diagram forming figur~ 27, which is self-explanatory. The essential lithologic similarity of the great bulk of these .deposits and their great vari­ ability, due to their littoral character and the reworkingtf unlithified deposits concomitant upon transgressions and withdrawals of the sea, inhibit th recogni.tion of physical ev1.· deuces . of unconformity. - To ignore for the present the restricted formationa names based on local lithologic characters, the standard section of the Eocene may be sai to comprise a series of formations assembled in groups, at their base restmg upon Upper ~retaceous rocks and succeeded by deposits of Oligocene age.
