Forest Biomass Estimation Based on Remote Sensing Method for North Daxingan Mountains
BP Neutral Net Forest Biomass Landsat TM Data Multiple Linear Regression
2011/12/20
Using the Landsat 5 TM images in 2002 as source data，the paper constructed individual tree biomass models of seven principal species based on the data from field surveying and fixed Plots in Tahe and ...
Forest Biomass Estimation Based on Forest Inventory Data in Middle and Last Scales
Forest Biomass Forest Inventory Data Maoershan Forest Farm
2011/12/20
The forest biomass (which is referred to the arbor aboveground biomass in this research) is one of the most primary factors to determine the forest ecosystem carbon storages. There are many kinds of e...
Quantitative Estimation of Palygorskite using thermogravimetric Analysis in Paleosols from Sepahanshahr, Isfahan, Iran
Quantitative Estimation Palygorskite thermogravimetric Analysis
2011/11/4
Palygorskite accounts for a major portion of the minerals present in paleosols in the central Iranian plateau. The identification and quantitative determination of this clay mineral is of great import...
An Fe-Berthierine from a Cretaceous Laterite: Part II. Estimation Of Eh, pH and pCO2 Conditions of Formation
Berthierine Gibbsite Goethite Cretaceous Kaolinite pCO2 pH Siderite Soil Zone Weathering
2011/12/22
Abstract: Transgression by the Western Interior Sea during the Late Cretaceous in southwestern Minnesota caused swampy conditions to be imposed upon a laterite consisting of gibbsite, goethite and kao...
Estimation of the Zeolite Contents of Tuffaceous Samples from the Bigadic Clinoptilolite Deposit, Western Turkey
Clinoptilolite CO2 Adsorption Dubinin-Astakhov Isotherm Model Natural Zeolites NH4+-Exchange Zeolite Content
2011/12/27
Variation of the NH4+-exchange and CO2-adsorption capacities with zeolite content was investigated in detail to assess the potential use of these capacities for the estimation of the zeolite contents ...
Estimation of Heavy Atom Content and Distribution in Chlorite Using Corrected X-Ray Powder Diffraction Intensities
Chlorite Heavy atoms Intensity measurements Sample preparation X-ray powder diffraction
2012/1/9
The heavy atom content and distribution in chlorite were estimated using the relative intensities of basal X-ray powder diffraction (XRD) peaks. For these peaks to be meaningful, however, corrections ...

Abstract: As part of a laboratory study of the hydrothermal alteration of kimberlite, a mass balance procedure has been developed for estimating the relative proportions of synthetic phyllosilicate ph...
A Method for the Quantitative Estimation of Clay Minerals in North Pacific Deep-Sea Sediments
Clay Distribution Clay Quantification Deep-sea Pacific X-ray Methods
2012/2/9
The addition of a 10% talc internal standard to North Pacific sediments allows the relative abundances of clay minerals to be determined both accurately and precisely by X-ray powder diffractometry. L...
Quantitative Estimation of Kaolinite in Sediments by Differential Infrared Spectroscopy
Hydroxyl Kaolinite Sediments
2012/2/10
An infrared method has been developed for estimating kaolinite in sediments. Hydroxyl stretching bands of kaolinite in sediments can be recorded by using a differential technique which eliminates the ...
