Tectonophysicochemistry　is　an　emerging　study　direotion　in　geomechanics　within　the　field　of　＂　struc-ture-oombined　construction＂.　It　has　developed　into　an　interdisciplinary　field　that　studies　the　eorrelation　between　the　physical　and　ehemieal　ehanges　of　roeks　during　tectonic　aetivities.　In　addressing　the　ehallenging　problem　in　earth　sciences,　namely　＂whether　tectonic　force　can　affect　ehemieal　equilibrium＂,　the　author　condueted　in-depth　research　on　the　geological　struetures　of　ore　fields　and　explored　the　influence　of　tectonic　force　on　pressure.　The　tectonic　stress　field　can　be　divided　into　two　parts:　one　is　the　stress　difference,　which　causes　the　deformation　of　rocks;　and　the　other　is　the　average　stress,　which　is　the　positive　pressure　stress　State　of　equal　directions　that　ehanges　the　volume　of　rocks.　The　latter　is　called　＂structural　additional　hydrostatic　pressure＂.　The　＂tectonic　ad-ditional　hydrostatic　pressure＂　is　superimposed　on　the　pressure　caused　by　its　geological　processes,　altering　the　pressure　at　a　given　point　and　affecting　other　physical　and　ehemieal　conditions,　thus　Controlling　the　diagenetic　and　geochemical　processes　of　diagenesis　and　mineralization.　Tectonophysicochemistry　is　the　study　of　＂　how　tectonic　forces　change　the　physicochemical　conditions　and　then　affect　the　ehemieal　process＂.　It　focuses　on　structural　additional　pressure,　temperature,　and　other　physicochemical　conditions　caused　by　tectonism　and　their　control　over　physicochemical　processes.　The　prediction　of　＂second　enrichment　zone＂　deep　in　Jiaodong　gold　deposit,　u-sing　theories　and　methods　such　as　tectonophysicochemistry　and　＂structural　correction　of　metallogenic　depth＂　has　been　confirmed.　This　provides　theoretical　and　methodological　support　for　Jiaodong,　the　third-largest　gold　region　in　the　world.　After　more　than　30　years　of　scientific　research　and　prospecting　practices,　tectonophysicochemistry　has　gained　extensive　academic　influence.　The　Geomechanics　Committee　of　the　Geological　Society　of　China　es-tablished　the　＂Professional　Group　of　Tectonophysicochemistry＂　in　1996,　and　the　Chinese　Geophysical　Society　approved　the　establishment　of　the　＂Professional　Committee　of　Tectonophysicochemistry＂　in　2018.　The　problems　in　tectonophysicochemistry　that　need　further　study　are:　additional　hydrostatic　pressure,　tectonism　affecting　temperature,　tectonism　changing　physical　properties　of　rock,　tectonism　affecting　geological　PT　phase　diagram,　and　developing　methods　for　observing　and　studying　structural　deformation　lithofacies.　Tectonophysicochemistry　has　made　significant　progress　in　various　areas,　including　the　expansion　and　application　of　abnormal　crustal　pressure　and　deep　crustal　pressure　states,　tectonic　driving　and　trapping　of　oil　and　gas,　tectonic　correction　calculation　of　diagenetic　and　metallogenic　depth　and　prediction　of　hidden　ore　deposits,　＂　crustal　genesis　of　tectonic　pressuriza-tion＂　in　ultra-high-pressure　metamorphic　belt,　physicochemical　conditions　of　coal　deformation　and　metamor-phism,　thermodynamic　analysis　of　critical　mineralization,　tectonophysicochemical　constraints　of　earthquake　dis-aster　fluid　on　rock　System,　and　geophysical　exploration　based　on　tectonic　deformation　lithofacies　belts.　There　is　a　broad　prospect　for　the　development　of　tectonophysicochemistry.　©　2024　China　University　of　Geosciences.　All　rights　reserved.
