The Church of the Company of Jesus in Quito (1605–1765) is one of the most remarkable examples of colonial religious architecture on the World Heritage List. This church has multiple constructive phases and several interventions with no clear record of the entire architectural site, including the historical mortars. A total of 14 samples of coating mortars inside the central nave were taken, with the protocols suggested by the research team and a comparative sample of the architectural group that does not have intervention. The analysis presented in this paper focuses on mineralogical characterization, semi-quantitative analysis by X-ray diffraction and scanning electron microscopy with microanalysis of the samples. The results showed the presence of volcanic aggregate lime and gypsum, used in lining mortars and joint mortars. Mineralogical and textural composition data have allowed the mortar samples to be relatively dated.

耶稣会教堂的迫击炮的特征和分析——基多（厄瓜多尔）

基多耶稣会教堂（1605-1765 年）是世界遗产名录上殖民时期宗教建筑最杰出的例子之一。这座教堂有多个建设阶段和几次干预，没有对整个建筑遗址的清晰记录，包括历史灰泥。根据研究团队建议的协议和没有干预的建筑团队的对比样本，共采集了 14 个中央中殿内的涂层砂浆样本。本文介绍的分析侧重于矿物学表征、X 射线衍射半定量分析和扫描电子显微镜以及对样品进行微量分析。结果表明火山骨料石灰和石膏的存在，用于衬砌砂浆和接缝砂浆。
