Selection and correct applying of the geosensor - the instrument of mineral geothermobarometry is challenging because of the wide variety of existing geosensors on the one hand and the availability of specific requirements for their use on the other. In this paper, organization of the geosensors within the computer system called interactive registry was proposed for reducing the labor intensity of the geosensors usage and providing information support for them. The article provides a formal description of the thermodynamic geosensor, as a function of the minerals composition and independent parameters, as well as the basic steps of pressure and temperature estimation which are common for all geosensors: conversion to the formula units, calculation of the additional parameters and the calculation of the required values. Existing collections of geosensors made as standalone applications, or as spreadsheets was examined for advantages and disadvantages of these approaches. Additional information necessary to use the geosensor was described: paragenesis, accuracy and range of parameter values, reference and others. Implementation of the geosensors registry as the webbased application which uses wiki technology was proposed. Usage of the wiki technology allows to effectively organize not so well formalized additional information about the geosensor and its algorithm which had written in a programming language into a single information system. For information organization links, namespaces and wiki markup was used. The article discusses the implementation of the applications on the top of DokuWiki system with specially designed RESTful server, allowing users to apply the geosensors from the registry to their own data. Programming language R uses as a geosensors description language. RServe server uses for calculations. The unittest for each geosensor allows to check the correctness of its implementation. The user interface of the application was developed as DokuWiki plug-in. The example of usage was given. In the article conclusion, the questions of the application security, performance and scaling was discussed.
