Taihu West Hill Geological Museum

Taihu West Hill Geological Museum

The Suzhou Taihu West Hill Geological Museum is the first national geological park museum in the province, with a construction area of 6,000 square meters. It houses multiple exhibition halls including the Earth Hall, Mineral Resources Hall, Geological Environment Hall, and Multi-functional Video Hall, comprehensively and multi-dimensionally showcasing the unique natural landscape resources of the Taihu basin such as tectonics, stratigraphy, paleontology, karst, and lake erosion.

The geological museum fully displays the natural, cultural, and geographical features of West Hill. It is a scientific tourism attraction and science education base that integrates exhibitions, collections, research, and education, characterized by scientific value, knowledge, aesthetics, and entertainment.

Exquisite Collections

Exquisite Collections — Fossils

Fossils, as objects of appreciation, are quite different from those of scientific research. The late Professor Yuan Kuirong proposed an eight-character evaluation principle: authenticity, rarity, peculiarity, form, spirit, color, and quality, pointing out that "authenticity" is the primary prerequisite, while "form and spirit" are the essence of evaluation and the source of aesthetic value; whereas "rarity, peculiarity, color, quality, and quantity" are supplementary evaluation criteria.

Exquisite Collections — Minerals

Minerals are crystalline compounds or elements formed by geological processes. Generally, minerals have relatively stable chemical compositions and crystal structures, and exist stably within certain physicochemical conditions. They represent a form of movement and presence of chemical elements during the evolution of the Earth, and are also the smallest units that make up crustal rocks.

The formation of minerals can basically be categorized into three types: transformation from gaseous to solid, from liquid to solid, and from solid to solid. Among these, the transition from liquid to solid is the most important method. However, regardless of the formation method, minerals must meet specific physicochemical conditions such as temperature, pressure, component concentration, acidity or alkalinity (pH), and redox potential (Eh).

Mineral-based ornamental stones have distinct characteristics compared to rock-based ornamental stones, mainly in the following aspects: Crystal Form — Minerals all have certain crystallization habits, with 47 types of single forms such as cubes, rhombohedrons, pyramids, or pentagonal dodecahedra, among others. There are also twins and intergrowths. Therefore, the crystal form should be intact. Color — Minerals have relatively fixed chemical compositions, or if impurities are mixed in, they will display various specific colors.

Transparency — Transparency refers to how clearly objects behind a 1 cm thick mineral can be seen; if the details of the object’s outline are clearly visible, it is considered transparent, such as selenite, Iceland spar, or quartz; if only a vague outline of overlapping objects can be seen, it is translucent, such as light-colored sphalerite or cinnabar; if the objects behind are not visible at all, it is opaque, such as graphite, magnetite, or ferroan sphalerite.

Exquisite Collections — Rocks

There are three major types of rocks: igneous, sedimentary, and metamorphic. Due to their differing compositions, structures, textures, and formation histories, they offer different aesthetic experiences through their shape, color, pattern, texture, and sound, providing great scope for personification. Coupled with artistic processing by observers — such as naming, inscribing poetry, calligraphy, pairing with paintings, bases, combinations, and shaping the stone's environment — they ultimately become ornamental stones. Typically, ornamental stones are described by their shape, color, pattern, texture, and sound.

Shape — Refers to the external appearance of a rock, valued for being natural rather than artificially shaped. Due to various fissures, differing compositions, and combinations, rocks have varying resistance to wind, rain, and water erosion, resulting in a wide variety of shapes.

Exquisite Collections — Gemstones

Jade refers to non-metallic mineral cryptocrystalline aggregates produced in nature that are hard (generally with a Mohs hardness of 4 or above), brightly colored, strongly reflective after polishing, fine and tough in texture, and meet craft requirements. There are also very few metallic mineral aggregates, such as malachite.
