The program for the development of the national economy based on own mineral raw materials as adopted in the Socialist Republic of Vietnam requires an increase the volumes of minerals. This includes both liquid hydrocarbons, and non-traditional solid minerals. This paper examines the resource base of mineral deposits in the South China Sea. The objective was to determine and scientifically establish classification criteria for zoning (regionalization), as well as to identify prospective areas with deposits of ferromanganese formations and other solid minerals. An analysis was undertaken of placers on the shelf and deposits of ferromanganese formations in the deep areas of the Vietnam Sea. A multiparameter analysis of the hydrological, geophysical, engineering and geological, environmental conditions of the deposit positions was conducted. In addition, criteria for the prospects of the formation and development of deposits of ferromanganese formations were established. These criteria enabled areas with different prospectivity ratings to be identified. Within the South China Sea, zones (areas) with a high, medium, and low potential for the presence of nodules were identified. Similar zoning for the crusts was also identified. The areas of these zones were determined. The results of the research established that the total potential area of ferromanganese nodules is 91,480 km2. The area with the potential of ferromanganese crusts is 2,421.6 km2, while the area of coexistence of nodules and crusts is 18,777 km2. Furthermore, priority regions for future exploration are those with high nodule potential covering an area of 18,110 km2 and the regions of high crust potential with an area of 882.6 km2. Based on the materials obtained, the bed of the Vietnamese Exclusive Zone of the South China Sea was zoned. Maps of the resource and predictive prospects of the seabed were drawn, and the prospecting and exploration operations can be established within this framework.

Принятая в Социалистической Республике Вьетнам программа развития народного хозяйства, базирующегося на собственной минерально-сырьевой базе, требует повышения объемов добычи полезных ископаемых, в том числе жидких углеводородов, вовлечения нетрадиционных видов твердых полезных ископаемых. Исследована ресурсная база месторождений полезных ископаемых Южно-Китайского моря. Идея исследований заключалась в определении и научном обосновании классификационных критериев зонирования (районирования) и выделении перспективных участков с залежами железомарганцевых образований и других твердых полезных ископаемых. Проведен анализ россыпных месторождений на шельфе и залежей железомарганцевых образований в глубинных районах Вьетнамского моря. Проведен многосторонний анализ гидрологических, геофизических, инженерно-геологических, экологических условий залегания месторождений, определены критерии перспективности образования и развития залежей железомарганцевых образований. Эти критерии позволили произвести выделение участков с различным рейтингом перспективности. В пределах Южно-Китайского моря выделены зоны (участки) с высоким, средним и низким потенциалом нахождения конкреций, а также выявлена аналогичная зональность для корок. Определены площади указанных зон. Результаты исследований показали, что общая потенциальная площадь железомарганцевых конкреций составляет 91 480 км2, площадь с потенциалом железомарганцевых корок – 2421,6 км2 и площадь сосуществования конкреций и корок – 18 777 км2. При этом приоритетными районами для будущих разведок являются районы с высоким потенциалом конкреций площадью 18 110 км2 и районы с высоким потенциалом корок площадью 882,6 км2. На основании полученных материалов произведено районирование дна Вьетнамской эксклюзивной зоны Южно-Китайского моря и составлены карты ресурсно-прогнозной перспективности морского дна, в пределах которых необходимо организовывать поисково-разведочные работы.
