Great advances have been made on granitic structures and emplacement mechanisms in recent years. Studies on many granitoid plutons in different orogenic belts have got new conclusions: granitoid plutons not only emplaced in the regional extension setting, but also in the regional compressive (shortening) setting. The relationship between granitoid plutons and faults has been attentively investigated in orogenic belts recently. It is much unlikely thought before that emplaced granitoid pluton had been controlled by faults or fractures. In fact, the process of intruding and opening space must have been controlled by multiple emplacement mechanisms. Meanwhile, study on structural patterns and deformed fabrics of granitic pluton is the key to emplacement mechanisms. So we suggest some research ideas and methods in this paper: studies on vertical structural pattern, use aluminium-in- hornblende geobarometer to determine an emplaced depth, tectonic analyses and deformation sequences, quantification studies on multiple emplacement mechanisms, etc. At last, we discuss the Mesozoic granitic structures and emplacement mechanisms in Dabie mountain orogen.
