[Tex/LaTex] footnote in the figure caption (through \footnotetext , footnotemark) does not appear in the same page as the figure

floatsfootnotes

I have several figures in my thesis which need a footnote in their caption. However, I could not find an efficient way to do it looking into the others' inquiries in the forum. In fact, using the \footnotetext , \footnotemark as the following code, makes the footnote to be appeared in the page before the float. I tried some suggestions such as the minipage, \clearpage, etc., to adjust the problem, but they did not work. Anyone could help me? Would appreciate it!

\begin{figure}
 \centerline{\includegraphics[width=6.5cm]{./chapter2/Figures/couche2.png}}
 \caption{Lithostratigraphic profile of clay \protect\footnotemark.}
 \label{fig:couche2}
\end{figure}
\footnotetext{Lithostratigraphic ....}

Here a solution with afterpage package.

From the manual

This package implements a command, \afterpage, that causes the commands specified in its argument to be expanded after the current page is output.

\documentclass{report}
\usepackage{lipsum}
\usepackage{afterpage}
\usepackage{graphicx}  
\begin{document} 
\chapter{chapter one} 
\lipsum[1-3]

\afterpage{%
 \begin{figure}
 \centerline{\includegraphics[width=6.5cm]{example-image-a}}
 \caption{Lithostratigraphic profile of clay\protect\footnotemark.}
 \label{fig:couche2}
 \end{figure}
 \footnotetext{Lithostratigraphic ....}
}
\lipsum[1-6]
\end{document}

[Tex/LaTex] \footnotetext on different page from \footnotemark

This is unlikely to be able to be done in a satisfactory way. One could envision moving the \footnotetext around based on page references. That would likely work in some cases (but be a hassle to implement) but in some cases, moving the \footnotetext would case the figure to float to another page and thus the \footnotetext would have to move again. It's quite easy to imagine that the iterative process never terminating.

Another problem is that your footnotes will be out of order. This is very easy to demonstrate.

\documentclass{article}
\begin{document}
one\footnote{one}
\begin{figure}[t]
two\footnotemark
\end{figure}
\footnotetext{two}
three\footnote{three}
\end{document}

That's almost certainly not what you want.

In most cases, footnotes in figures (or more often in tables) use different markings like an asterisk or a dagger and then the text appears in the figure caption.

Put the \footnotetext{...} after the figure environment.

Edit: I also study the case when SCfigure is used together with minipage. Here \parbox is used instead of minipage though. Hope this will serve as a start.
