Impairment in the ability to detect certain emotions, such as fear, is linked to multiple disorders and follows a pattern of inter-individual variability and intra-individual stability over time. Deficits in fear recognition are often related to social and interpersonal difficulties but the mechanisms by which this processing deficit might occur are not well understood. One potential mechanism through which impaired fear detection may influence social competency is through diminished perspective-taking, the ability to perceive and consider the point of view of another individual. In the current study, we hypothesized that intra-individual variability in the accuracy of facial emotion recognition is linked to perspective-taking abilities in a well-characterized, non-clinical adult sample. Results indicated that the ability to accurately detect fear in the faces of others was positively correlated with perspective-taking, consistent with initial hypotheses. This relationship appeared to be unique to recognition of fear, as perspective-taking was not significantly associated with recognition of the other basic emotions. Results from this study represent an initial step towards establishing a potential mechanism between some processes of FER and perspective-taking difficulties. It is important to establish the relationship between these processes in a non-clinical adult sample so that we can consider the possibility of a developmental or pathological influence of impoverished perspective-taking on fear perception.

检测某些情绪（如恐惧）的能力受损与多种疾病有关，并随着时间的推移呈现出个体间可变性和个体内稳定性的模式。恐惧识别能力的缺陷往往与社交和人际交往困难有关，但这种处理缺陷的发生机制尚不十分清楚。恐惧识别能力受损可能影响社交能力的一个潜在机制是透视能力下降，即感知和考虑他人观点的能力下降。在本研究中，我们假设在一个特征明确的非临床成人样本中，面部情绪识别准确性的个体内变异与透视能力有关。结果表明，准确识别他人面部恐惧的能力与透视能力呈正相关，这与最初的假设一致。这种关系似乎只与识别恐惧有关，因为透视法与识别其他基本情绪并无显著关联。这项研究的结果为建立 FER 某些过程与透视困难之间的潜在机制迈出了第一步。在非临床成人样本中建立这些过程之间的关系非常重要，这样我们就可以考虑透视困难对恐惧知觉的发展或病理影响的可能性。

Distinguishing primary and mineralization-related signatures of chert from the banded iron-formation–hosted gold deposits at Musselwhite, Ontario and Meadowbank, Nunavut 安大略省Musselwhite和努纳武特Meadowbank带状含铁金矿床中燧石原生特征与成矿相关特征的区分

Algoma-type banded iron-formation units are generally Archean chemical sedimentary rocks comprised of alternating layers of iron-rich minerals and chert that are stratigraphically associated with submarine volcanic rocks and localized within greenstone belts. Although much research has been done on Algoma-type banded iron-formation units, their depositional and overall geological settings are contentious due to overprinting effects of postdepositional deformation and metamorphism and the absence of modern analogues for comparative studies. Geochemical study of the gold-hosting Algoma-type banded iron-formation units at the Musselwhite and Meadowbank deposits provide comparable information on their depositional context. Geochemical tools, such as rare-earth element REE+Y systematics, indicate that chert bands in Algoma-type banded iron-formation record contributions from: 1) seawater, characterized by enrichment in HREEs relative to LREEs, and positive La, Gd, and Y anomalies; 2) hydrothermal fluids, characterized by a positive Eu anomaly and a flat pattern; and 3) hydrogeneous contamination. A detailed study of both of the aforementioned deposits was undertaken to evaluate the origin of the chert in these banded iron-formation settings. A hydrothermal overprint on banded iron-formation from the Musselwhite deposit is proposed to explain negative Ce anomalies that may be due to late hydrothermal fluid circulation in the chert bands replacing the initial seawater component. This hydrothermal alteration phase may be associated with the gold mineralization.

阿尔戈马型带状铁形成单元一般为太古宙化学沉积岩，由富铁矿物和燧石层交替组成，地层上与海底火山岩相关，定位于绿岩带内。尽管对阿尔戈马型带状铁形成单元进行了大量研究，但由于沉积后变形和变质作用的叠加效应以及缺乏现代类似物进行比较研究，其沉积和整体地质背景存在争议。Musselwhite和Meadowbank矿床含金阿尔戈马型条带状铁成矿单元的地球化学研究为其沉积环境提供了可比较的信息。稀土元素REE+Y分系统等地球化学工具表明，阿尔戈马型带状铁地层中的燧石带记录了以下因素的贡献:1)海水以hree相对lree富集为特征，La、Gd、Y呈正异常;2)热液流体，以Eu正异常和扁平型为特征;3)氢污染。对上述两个矿床进行了详细的研究，以评估这些带状铁形成环境中燧石的起源。提出了贻贝白矿床带状铁形成的热液叠印，以解释可能由于燧石带晚期热液循环取代了最初的海水成分而导致的负Ce异常。该热液蚀变期可能与金矿化有关。
