Water in Lunar Pyroclastic Deposits : Linking Orbital Observations To
Introduction: Water (OH and/or H2O) on the lunar surface and preserved in lunar materials can record information about solar wind, cosmic ray, impact, and lunar interior processes. In particular, understanding if any lunar surface hydration signatures can be linked to endogenous (e.g., magmatic) sources has the potential to inform us of the nature and distribution of volatiles in the lunar inte...

country to the economic activity existing in developed countries. Incidentally, my planning office has just finished a feasibility study for an area in the Amazon Basin where 500 families may be settled in 14,400 hectares (1 hectare = 10,000 square meters), with a loan of $16,000 (United States dollars) per family extending over a 10-year period. After 10 years each family will have paid the lo...
متن کاملRemote Sensing of Lunar Pyroclastic Mantling Deposits
Mantling deposits on the Moon are considered to be pyroclastic units emplaced on the lunar surface as a result of explosive fire fountaining. These pyroclastic units are characterized as having low albedos, having smooth fine-textured surfaces, and consisting in part of homogeneous, Febearing volcanic glass and partially crystallized spheres. Mantling units exhibit low returns on depolarized 3....
متن کاملCompositional analyses of lunar pyroclastic deposits
The 5-band Clementine UVVIS data at 100 m/pixel were used to examine the compositions of 75 large and small lunar pyroclastic deposits (LPDs), and these were compared to representative lunar maria and highlands deposits. Results show that the albedo, spectral color, and inferred composition of most LPDs are similar to those of low-titanium, mature lunar maria. These LPDs may have consisted larg...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
