In this research the JPD method of processing of the BSE and CL images including plotting of JPD histograms and JPD maps of grains was developed and applied for quantitative study of the internal texture of zircon grains with micron spatial resolution and for its use in geochronometry. The nomenclature for distinguished zones on the generalized diagram (BSE vs. CL) is suggested for zircons of a wide range of the conditions of its formation, age, size, texture types, and degrees of structure disordering. The JPD-analysis of zircon internal texture is applied for interpretation of the nature of variations in the BSE and CL intensities within an individual heterogeneous grain (on the quantitative level) and between different grains (on the qualitative level). The approach is suggested as the preliminary stage during geochronological studies increasing the reliability of the local electron microprobe and mass spectrometry isotope dating of the mineral.</p></abstract><trans-abstract xml:lang="ru"><p>Полигенность и полихронность строения - ключевой источник информации об условиях роста и вторичных преобразований циркона. С целью количественного изучения внутреннего строения зёрен циркона с микронным пространственным разрешением и использования в геохронометрии развита и апробирована JPD‑методика обработки их BSE-, CL‑изображений. Для цирконов с широким диапазоном свойств предложена номенклатура для выделения отдельных зон на обобщенной диаграмме (BSE vs CL). JPD‑анализ использован для интерпретации на количественном уровне природы вариаций BSE- и CL‑интенсивностей внутри отдельного гетерогенного зерна и на качественном уровне - ​между различными зёрнами как предварительный этап при геохронологических построениях, повышающий надёжность локальных изотопных и химических датировок минерала.</p></trans-abstract><kwd-group xml:lang="en"><kwd>zircon</kwd><kwd>internal texture</kwd><kwd>joint image analysis</kwd><kwd>JPD analysis</kwd><kwd>cathodoluminescence</kwd><kwd>backscattered electrons</kwd><kwd>microanalysis</kwd><kwd>geochronology</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>циркон</kwd><kwd>внутреннее строение зёрен</kwd><kwd>совместный анализ изображений</kwd><kwd>JPD-анализ</kwd><kwd>катодолюминесценция</kwd><kwd>обратно рассеянные электроны</kwd><kwd>микроанализ</kwd><kwd>геохронология</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap></funding-source><award-id></award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский фонд фундаментальных исследований</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Corfu F., Hanchar J.M., Hoskin P.W.O., Kinny P.
