Introduction: Tagish Lake, an observed fall in the year 2000, was classified by [1] as a type 2 carbonaceous chondrite. It bears similarity to CI 1 and CM chondrites but is distinct from both. [2] noted that the overall trace elements abundance pattern in Tagish Lake is similar to those of CM chondrites indicating that Tagish Lake and CMs experienced very similar nebular processes. The mineralo...

The “Danxia landform” is an erosional landform type originally defined in China. It is characterized by redcolored sandstones and steep cliffs, and developed via long-term erosion. Detailed quantitative geomorphometric studies of the characteristics of Danxia landforms in China have not yet been conducted. Using GIS, we conducted DEM-based geomorphometric analyses of 42 watersheds on Mt. Danxia...

The adverb ”then” is among the most frequent English temporal adverbs, being also capable of filling a variety of semantic roles. The identification of anaphoric usages of ”then” is important for temporal expression resolution, while the temporal relationship usage is important for event ordering. Given that previous work has not tackled the identification and temporal resolution of anaphoric ”...

the use of temporary runoff and underground dried-up water courses has been implemented by managers in recentyears to compensate for water shortages in arid and semi-arid regions. one way to use this water is to set up anunderground sandy dam in front of such water courses; selecting a suitable water course is the most important issue ofsuch a purpose. in the present research, this matter was i...

Assessing the impact of glaciations on topography and co-evolution ice-sheet dynamics requires a thorough understanding factors that control fjord morphology. We investigate role lithology glacial valley form using topographic analyses numerical landscape evolution models. measure depths widths from East Central Greenland (68°N–75°N), find width, with wider fjords in softer rocks (i.e., sedimen...

Introduction: We present a spectral deconvolution technique and model based on the description of electronic transition absorption bands in continuumremoved spectra. The model differs from the standard gaussian modeling in the way the continuum is removed. An improved nonlinear curve fitting algorithm is used to fit the model to the data. The approach represents also an alternative to the MGM m...

The classification and identification of rock samples is an important part geological analysis. In order to reduce the cost prevent human subjective judgment from affecting results, use deep learning establish intelligent a new way. Based on convolutional neural network model AlexNet structure, migration for image set analysis established, automatic recognition lithology realized by using metho...
