Chemical analysisyielded CaO27.3, Al2O3 5.1, SiO2 3.1, SO3 12.8,B2o33.2, H2O 48.6, sum : 100.1 percent.-Charlesiteis hexagonal,probable spacegroup P3lc, with a = ll.16(l), c = 21.21(2)4. The strongest lines in the X-ray powder difraction pattern (d, IlIo, hkl) are: 9.70,100, 100;5.58, 80, 110;3.855,80, ll4;2.749,70,304;2.538,70,126;2.193,70,2261 404. Charlesite occurs as simple hexagonal crystals tabular on {0001} and has a perfect {10T0}cleavage. The densityis 1.77glcm3 (obs.) and 1.79glcms (calc.). Optically, charlesite is uniaxial( -) with a : | .492(3)and e : 1.475(3).It occurswith clinohedrite,ganophyllite, xonotlite, prehnite, roeblingite and other minerals in severalparageneses at Franklin, New Jersey.

Phytoliths of the Barstow Formation Through the Middle Miocene Climatic Optimum: Preliminary Findings Katharine M
Phytoliths of the Barstow Formation through the Middle Miocene Climatic Optimum: preliminary findings Katharine M. Loughney 1,2 and Selena Y. Smith 1, 1 Museum of Paleontology, University of Michigan, 1109 Geddes Ave., Ann Arbor, MI 48109 2 Department of Earth & Environmental Sciences, University of Michigan, 1100 North University Ave., Ann Arbor, MI 48109 abstract—The Middle Miocene Climatic Optimum (MMCO) was an interval of signif- icant warming between 17.0 – 14.0 Ma, and a record of the interval is preserved in its entirety in the type Barstow Formation (19.3 – 13.3 Ma) of southern California. In order to understand the biotic impacts of the MMCO, it is necessary to understand vegetation; however, macrofloral records from the middle Miocene in this region are rare and do not span the MMCO. Phytoliths (plant silica) can be preserved in continental sediments even when macrofossil or pollen remains are not, and they can be diagnostic of specific plant clades and/or functional groups, some of which are useful environmental indica- tors. Sixty-eight sediment samples were collected from 12 stratigraphic sections measured within the Barstow Formation in the Mud Hills, Calico Mountains, and Daggett Ridge, and 39 samples were processed for phytoliths. Ten samples yielded phytoliths, although phytoliths were rare in most of these samples. Paleosols from the uppermost part of the Barstow Formation yielded the most abundant and most diverse phytolith assemblages, including grass bilobates and echinate spheres of palms; grass phytoliths were also identi- fied in samples from the Owl Conglomerate and Middle members but were rare. These phytolith data provide evidence that grasses were present throughout deposition of the Barstow Formation, and that they coexisted with palms in mixed-vegetation habitats. -

Geologic Mapping, Rainbow Basin Field Trip Information
FIELD TRIP 1 Geologic Mapping, Rainbow Basin (Vicinity Barstow, California) Ge 101 Fall Quarter 2013 General Information: We will be departing at 8:00 a.m. on Friday, November 1 from the parking area in front of Arms ("Arms Circle"). Please arrive by 7:45 so there is time to get the trucks packed etc. Attached is a map of how to get to the field area. We will be staying in a motel in Barstow on Friday and Saturday nights (California Inn). We will depart from the motel parking lot for the field area at 8 a.m. on Saturday and Sunday mornings. We will leave the field area at 4 p.m. Sunday, and arrive back at Caltech by 7 p.m. Meals: Rainbow basin is remote and there are no options to purchase food there. We will make a brief stop at a supermarket in Barstow Friday morning to purchase lunch food, snacks and drinks. You may however opt to bring your own food and pack it in ice chests before we leave, up to and including three lunches, two breakfasts and two dinners. Prof. and TAs usually opt for breakfast at Carrows (a short drive from the motel) at 7 a.m., but the California Inn has a free breakfast. There are lots of restaurant options for dinner, from McDonalds up to various moderately priced restaurants. If you opt to purchase lunch food Friday morning in Barstow and otherwise eat in restaurants, you should budget about $80-100. Report: The field report will be an inked and colored geologic map with a map legend and cross section, plus a short description of the geologic history of the map area, listing events depicted on the geologic map, plus additional information compiled in Lab. -

Department of !PcX,rU\ a^/icJ OreO-^ Scf&PW The University of British Columbia Vancouver, Canada Date OeC S/79 DE-6 (2/88) Abstract The sanbornite deposits at Big Creek and Rush Creek, Fresno County, California are host to many rare barium silicates, including bigcreekite, UK6, walstromite and verplanckite. As part of this study I described the physical properties and solved the crystal structures of bigcreekite and UK6. In addition, I refined the crystal structures of walstromite and verplanckite. Bigcreekite, ideally BaSi205-4H20, is a newly identified mineral species that occurs along very thin transverse fractures in fairly well laminated quartz-rich sanbornite portions of the rock. -

A Specific Gravity Index for Minerats
A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951). -

Paleontological Resources
Draft DRECP and EIR/EIS CHAPTER III.10. PALEONTOLOGICAL RESOURCES III.10 PALEONTOLOGICAL RESOURCES A paleontological resource is defined in the federal Paleontological Resources Preservation Act (PRPA) as the “fossilized remains, traces, or imprints of organisms, preserved in or on the earth’s crust, that are of paleontological interest and that provide information about the history of life on earth” (16 United States Code [U.S.C.] 470aaa[1][c]). For the purpose of this analysis, a significant paleontological resource is “considered to be of scientific interest, including most vertebrate fossil remains and traces, and certain rare or unusual inverte- brate and plant fossils. A significant paleontological resource is considered to be scientifically important for one or more of the following reasons: It is a rare or previously unknown species It is of high quality and well preserved It preserves a previously unknown anatomical or other characteristic It provides new information about the history of life on earth It has identified educational or recreational value. Paleontological resources that may be considered not to have paleontological significance include those that lack provenance or context, lack physical integrity because of decay or natural erosion, or are overly redundant or otherwise not useful for academic research” (Bureau of Land Management [BLM] Instruction Memorandum [IM] 2009-011; included in Appendix R2). The intrinsic value of paleontological resources largely stems from the fact that fossils serve as the only direct evidence of prehistoric life. They are thus used to understand the history of life on Earth, the nature of past environments and climates, the biological mem- bership and structure of ancient ecosystems, and the pattern and process of organic evolution and extinction.
