a–c High-resolution (HR) TEM images and corresponding selected area electron diffraction (SAED) patterns depicting residual crystal planes along the [−100], [11-1], and [110] zone-axis for the plagioclase samples a CE-PL1, b CE-PL2, and c CE-PL3, respectively. The scale bar of HR-TEM images is 2 nm, and the scale bar of SAED patterns is 2 nm−1. The orange arrows represent the approximate implantation direction of solar wind particles.
