The Han-Dynasty tomb at the Lingsheng Lake in Dingtao,Shandong,is a large late Western Han tomb featuring a Huangchang Ticou structure.The main body of it was built from a framework of heartwood cypress logs that were piled up on top of one another,with one to two layers of inscribed gray-coloured bricks being laid on the outer side.Using devices such as a 3D super-depth microscope and scanning electron microscopy with energy-dispersive X-ray spectroscopy(SEM-EDX),this study conducted a systematic analysis of gray-coloured brick fragments from different areas around the guo chamber coffin in tomb no.M2.The results revealed that the bricks contained a large amount of silty material and a small amount of clay.The composition of light and heavy minerals in the bricks matched that of sedimentary rock.Sintered structures with fluorite and limestone used as fluxes,as well as rare-earth slag,were found in some of the brick samples.Based on the chemical composition and petrographic features of the bricks,it was determined that the raw materials likely came from the lakebed or swamp sediments in the southern part of Dayeze in Shandong.The place names inscribed on the gray-coloured bricks indicate the origin of the raw materials.
