A terrain-corrected, regional Bouguer gravity map of the area has been produced which reflects this complexity. This map is dominated by a northwest grade, which is apparently the result of a Paleozoic tectonic boundary. This boundary seems to have at least locally exerted control on younger features leading to considerable superposition of structures in the area. The Andean chain straddles the western coast of the South American continent, parallel to a subduction zone where the Nazca plate descends beneath the South American continental plate. The area of our research was located in the northern part of the Huanuco province. Four sites were surveyed. The gravity values were calculated dataset and Bouguer corrections were applied. Finally, a Bouguer anomaly map of Peru and Bouguer anomaly maps of sites was produced based on these data.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Сложная тектоническая история северной части провинции Хуануко создает большие трудности для геофизических исследований в этом районе. Составлена региональная карта гравитации Буге с поправкой на рельеф местности, которая отражает данную сложность. На карте преобладают северо-западные ориентировки, которые, судя по всему, являются результатом влияния палеозойской тектонической границы. Выдвигается версия, что эта граница, по крайней мере локально, контролировала позицию более молодых объектов и тем самым повлияла на значительное усложнение структур в этом районе. Андская горная цепь тянется вдоль западного побережья Южноамериканского континента параллельно зоне субдукции, где океаническая плита Наска погружается под южноамериканскую континентальную плиту. Район проведения исследований располагался в северной части провинции Хуануко. Были обследованы четыре участка. Значения гравитационного поля рассчитаны по набору данных с применением поправки Буге. На основе этих данных составлена карта аномалий Буге территории Перу и карты аномалий Буге на участках исследований.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gravity data</kwd><kwd>magnetic data</kwd><kwd>local anomaly</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гравиразведочные данные</kwd><kwd>магниторазведочные данные</kwd><kwd>локальные аномалии</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hermoza W, Brusset S, Baby P, Gil W, Roddaz M, Guerrero N, Bolaños R.
