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.

Note that the fine ablation features seen Lafayette was enriched in deuterium. The alteration on Lafayette have not been reported on any of the assemblages in Lafayette continue to be an active field Nakhla specimens. of research, because it has been shown that the alteration in Lafayette occurred on Mars.

  • Pyroclastic Flow Hazards
    Pyroclastic Flow Hazards Lecture Objectives -definition and characteristics -generation of pyroclastic flows -impacts and hazards What are pyroclastic flows? Pyroclastic flows are high- density mixtures of hot, dry rock fragments and hot gases that move away from the vent that erupted them at high speeds. Generation Mechanisms: -explosive eruption of molten or solid rock fragments, or both. -non-explosive eruption of lava when parts of dome or a thick lava flow collapses down a steep slope. Most pyroclastic flows consist of two parts: a basal flow of coarse fragments that moves along the ground, and a turbulent cloud of ash that rises above the basal flow. Ash may fall from this cloud over a wide area downwind from the pyroclastic flow. Mt. St. Helens Effects of pyroclastic flows A pyroclastic flow will destroy nearly everything in its path. With rock fragments ranging in size from ash to boulders traveling across the ground at speeds typically greater than 80 km per hour, pyroclastic flows knock down, shatter, bury or carry away nearly all objects and structures in their way. The extreme temperatures of rocks and gas inside pyroclastic flows, generally between 200°C and 700°C, can cause combustible material to burn, especially petroleum products, wood, vegetation, and houses. Pyroclastic flows vary considerably in size and speed, but even relatively small flows that move <5 km from a volcano can destroy buildings, forests, and farmland. On the margins of pyroclastic flows, death and serious injury to people and animals may result from burns and inhalation of hot ash and gases. Pyroclastic flows generally follow valleys or other low-lying areas and, depending on the volume of rock debris carried by the flow, they can deposit layers of loose rock fragments to depths ranging from less than one meter to more than 200 m.

Karasal ve gölsel fasiyesde meydana gelen Tersi- yer sedimanter kayaçlar Güney Eskişehir küvetinde olunmuşlardır. Karasal fasiye- si meydana getiren kayaç birimlerini kaba kumtaşları, kumtaşları, bitki kalıntıları ihtiva eden kil ve marnlar ve serpantinit blokları taşıyan bazal konglomerası teşkil etmektedir. Gölsel fasiyes ise genellikle killi ve tüflü kalkerler, kalkerler, marnlar, kon- glomeralar ve tüflerden meydana gelmiştir. Küvetteki en eski sedimanlar ve piroklas- tikler Alt Miosen'de oluşmuşlardır. Yataya yakın konumlanmış bazik-intermediyar lav akıntıları Pliosen yaşlı olup Altüst Neojen sedimantasyon kesikliğinde meyda- na gelmiştir.
