Through researching the regional and geological background and the ore structure of Lagaluo iron deposit, this paper describes the geological characteristics of Lagaluo iron deposit, and expounds the origin of deposit.

We find out the chemistry compositions,mineral compositions,ore structure,dissemination characteristics and particle size distributions of the target minerals and the liberations of the grinding products,and the analysis concerning with the factors affecting the performance of the ore dressing is done.

Energy analysis of rock structure under static and dynamic loading conditions

Illustrating with several interpretive result diagrams of logs in Changqing Oilfield,applications of the tool in fracture identification,rock structure and logging facies analysis,unconformable surface recognition,stress orientation analysis,sedimentary facies analysis,palaeocurrent direction analysis,etc.

A large amount of statistic results of interval transit time and porosity data of sandstone reservoir in the Tertiary of Jiyang Depression showed that the relation between interval transit time and porosity of sandstone was controlled by rock structure,which was affected by diagenesis.

Seismic properties of reservoir sandstones and their implication to rock texture in the Dongying Sag,the Bohai Bay Basin

Commonly used methods to quantify or semi-quantify rock textures are estimating through naked eyes,or through visual comparison charts,dot-counting,and image analyses.

In each change trend,with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content,the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix,which resulted in the measured data illustrating extremely different tendency.

According to the features of southern Fujian,and combined with the reinforcement principles of ancient architecture,it discusses the reinforcement strategies of ancient architecture in southern Fujian from the wooden structure reinforcement and block stone structure reinforcement.
