A summary of the results achieved in the geological-structural mapping, by potential fields and airborne gamma spectrometry data, of the units of igneous and metamorphic rocks in the western regions (Havana-Matanzas), central (Cienfuegos, Villa Clara-Sancti Spiritus) and central-eastern (Camagüey-Las Tunas-Holguín) of Cuba is presented. In addition, the structural- tectonic regionalization with hydrocarbon exploration purposes, focusing mapping of possible new oil-gas targets in the regions of Land Blocks 9, 23 and 17-18 are detailed in this volume. In certain case study locations (Majaguillar, North Motembo, Guamutas and Maniabón) reconnaissance work by a profile of Redox Complex (complex of unconventional geophysical-geochemical exploration techniques) was performed with positive results.
In an attempt to contribute to the geological-structural mapping of the metamorphic massif Isla de la Juventud, with emphasis on acid magmatism, the gravi-magnetometric data is used. According to the results, the presumed post metamorphic granitic bodies of low density are located, mainly, in the central and southwestern part of the massif. The granitic bodies apparently were introduced through the system of longitudinal faults (syn metamorphic) and transverse (post metamorphic) at the end of the process multyfolding and metamorphism of the massif sequences, taking a leading role the deep longitudinal fracture zones of sublatitudinal direction in the central and southern part of the massif. On the map of the magnetic field vertical derivative the anomalies, basically, reflected the direction and limits of the folded tectonic structure, the development area of volcanogenic rocks, the presumed development zones of migmatitic rocks and tectonised rocks in North and center of the massif, respectively, and the prevailing direction of the main tectonic dislocations.

本書呈現了在古巴西部(哈瓦那-馬坦薩斯)、中部(錫恩富戈斯、比利亞克拉-聖斯皮里圖斯)及中東部(卡馬圭-拉斯圖納斯-奧爾金)地區,利用潛勢場和空中伽瑪光譜數據進行的火成岩和變質岩單元的地質結構繪製所取得的結果摘要。此外,本卷詳細說明了以碳氫化合物勘探為目的的結構-構造區域劃分,重點繪製了在土地區塊9、23及17-18區域可能的新油氣目標。在某些案例研究地點(馬哈基拉、北莫滕博、瓜穆塔斯和馬尼亞邦),進行了由Redox Complex(一種非常規地球物理-地球化學勘探技術的複合體)進行的勘查工作,並取得了積極的結果。
為了貢獻於變質大塊島(Isla de la Juventud)的地質結構繪製,特別是強調酸性岩漿作用,使用了重力-磁力數據。根據結果,推測的低密度變質後花崗岩體主要位於大塊的中央和西南部。這些花崗岩體顯然是通過縱向斷層系統(變質期)和橫向斷層(變質後)在多重變形和變質過程結束時引入的,深層縱向斷裂帶在大塊的中央和南部發揮了主導作用。在磁場垂直導數圖上,異常基本上反映了摺曲構造的方向和界限、火山岩的發展區域、推測的混合岩和構造岩在大塊北部和中央的發展區域,以及主要構造位移的主導方向。
