Abstract: Regional tectonics not only facilitate the ascent and emplacement of the granitic intrusions but also control the final shapes of the intrusions. Analogue modeling is a critical method to study the magma emplacement. This paper reviewed the experimental set-up, materials and scaling used in previous analogue models related to magma emplacement, and summarized the influence of various parameters on the geometry of the intrusions in various tectonic settings. We suggested that: (1) the intrusion geometry is controlled by the characteristics of the country rocks in pre-kinematic static settings during tectonic quiescent stage. (2) In syn-kinematic settings during tectonic active stage, the intrusion geometry and deformation patterns of plutons are influenced by several parameters, including the thickness and rheological layering of the country rocks, velocity and total distance of displacement, velocity and total volume of magma injection, position of the injection inlet (magma channel), relative timing of tectonic activity and magma emplacement. Deformation can in turn control the shape of intrusions. (3) The parameters, such as
displacement velocity and injection velocity in different settings, have similar impact on the intrusion geometry. In addition, some limitations of analogue modeling method are also discussed. The CT technique and numerical modeling methods are suggested to be profitable supplementation of analogue modeling for the study in magma emplacement.
