Photo- graph from Field Museum Natural History, Chicago, number 62913. Introduction According to Graham et al. (1985), “a mass of about 800 grams was noticed by Farrington in 1931 in the geological collections in Purdue University in Lafayette Indiana.” It was first described by Nininger (1935) and Mason (1962). Lafayette is very similar to the Nakhla and Governador Valadares meteorites, but apparently distinct from them (Berkley et al. 1980). Lafayette is a single stone with a fusion crust showing Figure 3.

The specimen is 62917. shaped like a rounded cone with a blunt bottom end. It was apparently oriented during entry into the Earth’s that the water released during stepwise heating of atmosphere. Note that the fine ablation features seen Lafayette was enriched in deuterium.

Tryon Creek Restoration Monitoring Project
Restoring Fish Passage in Tryon Creek (OR): Lampreys (NFWF 2006-0175-004) Final Programmatic Report T.A. Whitesel, G.S. Silver, C.W. Luzier, and J.M. Hudson U.S. Fish and Wildlife Service – Columbia River Fisheries Program Office 1211 SE Cardinal Ct – Ste 100 Vancouver, WA 98606 Introduction Tryon Creek is located in southwest Portland and its headwaters are located within those neighborhoods (Figure 1). It flows approximately 5 km through this privately owned land before entering Tryon Creek State Natural Area, a 259 hectare area of public land, through which the stream flows another 5 km. The lower most portion of Tryon Creek flows through public land owned by the City of Lake Oswego and the City of Portland. This portion of the stream is bisected by a culvert that runs under Oregon Highway 43 and a railroad near the mouth of Tryon Creek. Figure 1. Tryon Creek watershed. 1 Tryon Creek is one of the largest, relatively protected, urban watersheds in Oregon. A number of native species can currently be found in this stream including Oncorhynchus mykiss (resident and anadromous) and coastal cutthroat trout (O. clarki) (Tinus et al. 2003) as well as coho salmon (O. kisutch, Hudson et al. 2007) and Chinook salmon (O.tshawytscha) . Historically, it is thought that Pacific lamprey (Entosphenus tridentatus) and western brook lamprey (Lampetra richardsoni) as well as other salmon species also utilized this stream. However, the culvert under Highway 43 and the adjacent railroad is potentially inhibiting, if not preventing, passage of lampreys and salmonids. The Highway 43 culvert was constructed in the late 1920s. -

Aqueous Alteration of Yamato 000749 Based on Multi-Probe Microscopic Observation
Aqueous alteration of Yamato 000749 based on multi-probe microscopic observation Naoki Shiraishi1, Hiroki Suga1,2, Masaaki Miyahara1, Takuji Ohigashi3, Yuichi Inagaki3, Akira Yamaguchi4, Naotaka Tomioka 5, Yu Kodama6, and Eiji Ohtani7 1Hiroshima University, 2The University of Tokyo, 3UVSOR synchrotron facility, 4NIPR, 5Kochi Institute for Core Sample 6 7 Research, JAMSTEC, Marine Works Japan, Tohoku University Motivation Based on the results of Mars explorations and researches of Martian meteorites for many years, there is a high possibility that liquid water had existed extensively on Mars for a long time (Sekine, 2012). Martian meteorite is one of the important clues for restoring the past Martian surface environment that cannot be unveiled by Mars surface survey alone. It is expected that a member of Martian meteorites, nakhlites have evidences for a rock-fluid reaction occurred on Mars. One of the representative evidence for the rock-fluid reaction is “iddingsite”, which is an alteration texture formed in and around olivine grains in nakhlites. Many kinds of secondary minerals occur in the iddingsite through the rock-fluid reaction. The mineral assemblages, chemical compositions and chemical species of the secondary minerals depend on the varied parameters such as temperature and pH of the fluid. Suga et al. (2017) described the secondary minerals in the iddingsite of nakhlites Yamato (Y) 000593. Another Martian meteorites, Yamato (Y) 000749 is also a member of Yamato 00 nakhlites like Y 000593, containing abundant iddingsite. Based on Cohen et al. (2017), Y 000749 was located at the lower portion of the same nakhlites source compared to Y 000593. It is likely that these nakhlites have different mode of alteration even in the same source. -
